Changes since version 1.4:
* Fixed memory leaks in messagebase and subfields operations
* Added some sanity checks. Documentation updated.
* Compile-time configurable file locking method - lockf(3) vs. fcntl(2).
* Fixed infinite loop in JAM_CreateMB that happens if newly
created messagebase can not be locked.
* Eliminated (I hope) compiler warnings about uchar/ulong/ushort
on FreeBSD.
* QNX support.
Changes since version 1.3:
* Win32 support via autoconf
* JAM_ChangeMsgHeader() now updates UserCRC in index and ActiveMsgs
in header if message's Attribute contains MSG_DELETED.
* New function JAM_DeleteMessage() - delete message from
messagebase by setting HdrOffset and UserCRC to 0xFFFFFFFF.
Changes since version 1.2:
* JAM_AddMessage() would fail when trying to add an empty message
to the messagebase under Linux. Fixed.
* Moved to GNU autotools
Changes since version 1.1:
* Since JAM_GetSubField() is not reentrant and cannot be used in
multi-threaded applications, JAM_GetSubField_R() was added as a
replacement for cases where a reentrant function is needed.
Changes since varsion 1.0:
* Added support for Win32 and Linux
* Added JAM_AddEmptyMessage()
* Rewrote the Makefiles
* Rewrote the CRC32 routine
* Fixed broken JAM_FindUser()
* Fixed broken JAM_GetSubfield()
* Changed JAM_OpenMB so that files are opened in binary mode. This is
necessary to use JAMLIB under Windows.
* Improved JAM_ReadMsgHeader() to give the error JAM_NO_MESSAGE if
the message no longer exists in the messagebase and JAM_CORRUPT_MSG
if the subfields of the message have been corrupted.
* Improved portability by changing JAMLIB so that it no longer reads
and writes stuctures directly using fread() and fwrite().
* Improved ANSI-C compatibilty by no longer including the non-ANSI
header file memory.h and using feof() to check for EOF instead of
errno == EPASTEOF.
* Added an #ifdef so that ushort and ulong are no longer defined in
jam.h when compiling under Linux. These are normally already defined
in the standard header files.

Basic Installation
==================
These are generic installation instructions.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, a file
`config.cache' that saves the results of its tests to speed up
reconfiguring, and a file `config.log' containing compiler output
(useful mainly for debugging `configure').
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If at some point `config.cache'
contains results you don't want to keep, you may remove or edit it.
The file `configure.in' is used to create `configure' by a program
called `autoconf'. You only need `configure.in' if you want to change
it or regenerate `configure' using a newer version of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
Running `configure' takes awhile. While running, it prints some
messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that
the `configure' script does not know about. You can give `configure'
initial values for variables by setting them in the environment. Using
a Bourne-compatible shell, you can do that on the command line like
this:
CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
Or on systems that have the `env' program, you can do it like this:
env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you must use a version of `make' that
supports the `VPATH' variable, such as GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
If you have to use a `make' that does not supports the `VPATH'
variable, you have to compile the package for one architecture at a time
in the source code directory. After you have installed the package for
one architecture, use `make distclean' before reconfiguring for another
architecture.
Installation Names
==================
By default, `make install' will install the package's files in
`/usr/local/bin', `/usr/local/man', etc. You can specify an
installation prefix other than `/usr/local' by giving `configure' the
option `--prefix=PATH'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
give `configure' the option `--exec-prefix=PATH', the package will use
PATH as the prefix for installing programs and libraries.
Documentation and other data files will still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=PATH' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Specifying the System Type
==========================
There may be some features `configure' can not figure out
automatically, but needs to determine by the type of host the package
will run on. Usually `configure' can figure that out, but if it prints
a message saying it can not guess the host type, give it the
`--host=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name with three fields:
CPU-COMPANY-SYSTEM
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the host type.
If you are building compiler tools for cross-compiling, you can also
use the `--target=TYPE' option to select the type of system they will
produce code for and the `--build=TYPE' option to select the type of
system on which you are compiling the package.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share,
you can create a site shell script called `config.site' that gives
default values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Operation Controls
==================
`configure' recognizes the following options to control how it
operates.
`--cache-file=FILE'
Use and save the results of the tests in FILE instead of
`./config.cache'. Set FILE to `/dev/null' to disable caching, for
debugging `configure'.
`--help'
Print a summary of the options to `configure', and exit.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`--version'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`configure' also accepts some other, not widely useful, options.

This is the JAMLIB library by Björn Stenberg with some minor modifications
made by Johan Billing and Sir Raorn. You can find the documentation for
JAMLIB in the file jamlib.doc.
These are the modifications done by Johan Billing:
* Support for Win32 and Linux added
* JAM_ReadMsgHeader() now gives the error JAM_NO_MESSAGE if the
message has been removed from the messagebase (both offset and
crc are -1 in the index file).
* The function JAM_AddEmptyMessage() has been added
* Improved ANSI-C compatibilty by changing the header files
included and using feof() to check for EOF.
* JAMLIB been rewritten so that it no longer reads or writes structs
directly from or to disk. This makes JAMLIB more portable and ensures
that the Intel byte-order is used on all platforms.
* Some other bugfixes
These are the modifications done by Sir Raorn:
* All non-linux code dropped out (patches for mingw/djgpp/etc are welcome)
* Moved to autoconf/automake/libtool
Have a nice programming! :-)

## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse

## This next piece of magic avoids the `deleted header file' problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do

.TH JAMLIB 3 2002-11-07 "" "JAM subroutine library"
.SH NAME
jamlib \- a JAM subroutine library
.SH DESCRIPTION
These are a collection of subroutines that encapsulate much of the
format\-specific and tedious details of the JAM message base format. The
idea is that application programmers by using these routines can
concentrate on the more high\-level issues of their programs instead of
worrying about their JAM routines.
.PP
I [Bjorn Stenberg] wrote these routines primarily because I needed
them myself. I was trying to implement JAM support in my FrexxLink BBS
system and was frustrated by the poor level of documentation supplied in
the JAMAPI archive distributed by the JAM authors. Finally, I dove into
the JAMAPI source code in a desperate attempt at finding out how to use it.
To my despair, I discovered that the JAMAPI is targeted at a very low level.
I would need to implement a lot of JAM\-handling code into my own program.
.PP
This library is an attempt to do two things:
.PP
Firstly, provide an, at least sparingly, \fIdocumented\fP API, allowing
application programmers to easily implement JAM into their programs.
.PP
Secondly, raise the level of functionality above that of the original
JAMAPI package, so that the application programmer does not have to learn
and understand all the internals of the JAM message base format to
implement support for it.
.PP
I have not succeded completely on any of the two points, of course.
Documentation can never be too good, and there are still a few things about
JAM you must know in order to use it. But I think I have made it somewhat
easier than perhaps was the case before.
.sp
.SS "The Source Code"
I made a point of making this library as system independant as I could.
Only one function needs to be altered when porting this to another system:
The file locking. ANSI C does not include file locking so there is not much
I can do about it.
.PP
The choice of C over C++ is a part of this philosophy aswell. More
systems have C compilers than C++ compilers, and more people know C than
C++. Also, converting this library to a C++ class should be fairly simple.
If you do, send me a copy.
.PP
I use some naming conventions throughout the code and in the examples.
These are invented by myself as a reaction to the stunningly ugly and
hard\-to\-read Hungarian Notation promoted by some people. The rules of my
notation are simple:
.PP
.TP
\(bu
All library\-global identifiers are prefixed with \'\fBJAM_\fP\'. All
file\-global identifiers are prefixed with \'\fBjam_\fP\'. Local
identifiers do not have prefixes.
.TP
\(bu
All variables have a suffix describing their basic type. Suffixes used
in this library are:
.nf
_I \- integer (int Example_I)
_C \- character (char Example_C)
_S \- struct (struct Example_S)
_P \- pointer (void* Example_P)
_A \- array
.fi
.sp
Suffixes are then combined, to show the correct type:
.nf
_PI \- pointer to integer (int* Example_PI)
_PC \- pointer to char (char* Example_PC)
_AC \- array of char (char Example_AC[x])
_PPS \- pointer to pointer to struct (struct** Example_PPS)
.fi
.TP
\(bu
Functions do not have suffixes
.PP
The whole idea is that it is quicker to read and comprehend a
variable called \'\fIText_PC\fP\' than one called \'\fIpszText\fP\'.
We read from left to right, and thus the most important
information \- the name \- should be the leftmost data in the
word. The variable type is additional information and is
therefore added to the end where it does not disturb the reader.
.sp
.SS "The Functions"
The library is divided into five groups:
.TP
\(bu
Message base functions
.TP
\(bu
Message functions
.TP
\(bu
Subfield functions
.TP
\(bu
LastRead functions
.TP
\(bu
Miscellanous functions
.sp
.SS "Message base functions"
These functions handle JAM message bases, by opening, locking, scanning
etc the contents of a message base. These are fairly straight\-forward and
simple routines that you should have little, if any, trouble with.
.PP
A message base is identified by a message base handle, which is obtained
from either
.BR JAM_OpenMB (3)
or
.BR JAM_CreateMB (3).
All functions that read or
write from the message base take this handle as parameter, to know which
message base to use.
.PP
.TP
.BR JAM_OpenMB (3)
Open a message base
.TP
.BR JAM_CloseMB (3)
Close message base
.TP
.BR JAM_CreateMB (3)
Create a new message base
.TP
.BR JAM_RemoveMB (3)
Remove a message base
.TP
.BR JAM_LockMB (3)
Lock message base for exclusive access
.TP
.BR JAM_UnlockMB (3)
Unlock message base
.TP
.BR JAM_ReadMBHeader (3)
Read message base header
.TP
.BR JAM_WriteMBHeader (3)
Write message base header
.TP
.BR JAM_FindUser (3)
Find message to a user
.TP
.BR JAM_GetMBSize (3)
Get the number of messages in message base
.sp
.SS "Message functions"
These functions handle individual JAM messages. A JAM message contains of
three parts:
.sp
.TP
\(bu
Message Header
.TP
\(bu
Message Header Subfields
.TP
\(bu
Message Text
.PP
The message header is a simple C structure and the message text is a
simple text buffer.
.PP
The subfields, however, are a bit more tricky. These contain
everything that is not covered by the header, including the
\fBTO\fP, \fBFROM\fP, \fBSUBJECT\fP fields, origin and
destination network adresses etc. There can be an unlimited
number of subfields to a message.
.PP
In this routine library the subfields are encapsulated by a
\'\fIsubfield packet\fP\', which is handled by its own set of
routines. See a later section of this document for an
explanation of those.
.PP
.TP
.BR JAM_ReadMsgHeader (3)
Read a message\'s header and its subfields
.TP
.BR JAM_ReadMsgText (3)
Read a message\'s text
.TP
.BR JAM_AddMessage (3)
Add a message to message base
.TP
.BR JAM_AddEmptyMessage (3)
Add a empty message entry to a message base
.TP
.BR JAM_ChangeMsgHeader (3)
Change a message\'s header
.TP
.BR JAM_ClearMsgHeader (3)
Clear a message header structure
.TP
.BR JAM_DeleteMessage (3)
Delete message from messagebase
.sp
.SS "Subfield functions"
As described earlier, a subfield is a part of the message header. Due to
the complexity of the different network types in use, it is not feasible to
try and cram all data into one header struct. Therefore, JAM uses a fairly
small header struct and instead marks all additional data fields as
\'\fIsubfields\fP\'.
.PP
In order to make life a little more easy, I have used the concept of a
container for all subfields. I call it a \'\fISubfield Packet\fP\'. It is
identified by a struct pointer, and should be looked upon as a file or a
list that you manipulate via the following five functions:
.PP
.TP
.BR JAM_NewSubPacket (3)
Create a new subfield packet
.TP
.BR JAM_DelSubPacket (3)
Delete a subfield packet
.TP
.BR JAM_GetSubfield (3)
Get a subfield from a subfield packet (not reentrant)
.TP
.BR JAM_GetSubfield_R (3)
Get a subfield from a subfield packet (reentrant)
.TP
.BR JAM_PutSubfield (3)
Put a subfield into a subfield packet
.sp
.SS "LastRead functions"
JAM implements the often\-used concept of high water marking for
remembering which user read how many messages in each area.
.PP
Personally I think this concept stinks, since it does not store *which*
messages a user has read, only the number of the highest message he has
read. But since it\'s a part of JAM and it\'s fairly straightforward and
easy, I\'ve implemented two support functions for it.
.PP
I would, however, strongly recommend all BBS programmers to use proper
message mapping systems instead, so your users can read their messages in
whatever order they wish.
.PP
.TP
.BR JAM_ReadLastRead (3)
Read a lastread record
.TP
.BR JAM_WriteLastRead (3)
Write a lastread record
.sp
.SS "Miscellanous functions"
.PP
.TP
.BR JAM_Crc32 (3)
Calculate CRC32 on a block of data
.TP
.BR JAM_Errno (3)
Specify I/O error
.sp
.SH HISTORY
JAMLIB 1.0 was originally released by Bjorn Stenberg 1996\-03\-06.
Since the original license did not permit modification of the
library, Johan Billing contacted Bjorn Stenberg and asked him to
change the license. Bjorn Stenberg agreed to change the license
to the GNU Lesser General Public
License 1999\-12\-21.
.PP
After that, some minor additions and bug fixes were made by Johan
Billing and JAMLIB 1.1 was released under the new license.
.PP
Somewhen, after 1.2 release or so, Sir Raorn moved JAMlib to GNU
autotools, again with some minor additions an bugfixes.
.SH AUTHOR
All original code except for the CRC32 routine was written by Bjorn
Stenberg. The CRC32 code was rewritten by Johan Billing for JAMLIB 1.1
to replace the original CRC32 code whose origin and copyright was unclear.
The jam.h header file is a compilation of the best from the various header
files in the JAMAPI package with some of additions by Bjorn Stenberg as well.
Additions and modifications by Johan Billing and Sir Raorn.

This manual page was created by Sir Raorn <raorn@altlinux.ru>,
based on original JAMlib documentation by Bjorn Stenberg
<bjorn@haxx.nu> and Johan Billing <billing@df.lth.se>.
.SH "SEE ALSO"
If you are extra curious about the JAM message format, I suggest
you get a hold of an archive called \fIJAMAPI.ARJ\fP. That archive
contains a file called JAM.DOC which is the file I have used as
reference for the development of these routines.

- Changed source to use feof() instead of errno == EPASTEOF
- Changed source to use structrw to read and write structures
- Added JAM_AddEmptyMessage()
- Added error messages JAM_NO_MESSAGE and JAM_CORRUPT_MSG for
JAM_ReadMsgHeader()
- #includes stdlib.h instead of malloc.h and memory.h
Changes made by Sir Raorn 2001-12-08:
- Added JAM_DeleteMessage()

JAMLIB 1.0 was originally released by Björn Stenberg 1996-03-06. Since
the original license did not permit modification of the library,
Johan Billing contacted Björn Stenberg and asked him to change the

After that, some minor additions and bug fixes were made by Johan
Billing and JAMLIB 1.1 was released under the new license.
Changes in 1.3.2:
* Updated the Win32-specific parts of the code to make it compatible with
newer versions of MinGW (tested with 3.1.0-1).
Changes in 1.3.1:
* Backported the following bugfixes and improvements from JAMLIB 1.4.7 while
retaining the platform-independence and high portability of the early
versions of JAMLIB.
- JAMLIB now uses calloc() instead of malloc() followed by memset()
- JAM_OpenMB() and JAM_CreateMB() will set (*NewArea_PPS) to NULL if
calloc() failed
- JAM_CreateMB() no longer attempts indefinitely to lock the newly created
messagebase. If the first attempt fails, it will return an error.
- jam_Lock() now sets Base_PS->Errno under Linux
- JAM_NewSubPacket() and JAM_PutSubField() would give memory leaks under
conditions of low memory conditions. Fixed.
- JAM_ReadMsgHeader() would give memory leaks on failure. Fixed.
- Added JAM_DeleteMessage()
Big thanks to Sir Raorn (and others?) for finding and fixing these bugs!
* JAM_CreateMB() would never unlock or close the newly created messagebase
upon failure. Fixed.
* Improved handling of ActiveMsgs counter. JAM_AddMessage() now only
increases ActiveMsgs if the added message does not have MSG_DELETED set.
JAM_ChangeMsgHeader() decreases ActiveMsgs if MSG_DELETED is set and the
message wasn't already deleted. JAM_DeleteMessage() now only decreases
ActiveMsgs if the message wasn't already deleted.
* Updated the documentation to reflect the need to free() memory after
JAM_CloseMB() and failed calls to JAM_OpenMB() and JAM_CreateMB().
* Eliminated compiler warnings
Changes in 1.3:
* JAM_AddMessage() would fail when trying to add an empty message
to the messagebase under Linux. Fixed.
Changes in 1.2:
* Since JAM_GetSubField() is not reentrant and cannot be used in
* Since JAM_GetSubField() is not reentrant and cannot be used in
multi-threaded applications, JAM_GetSubField_R() was added as a
replacement for cases where a reentrant function is needed.

Changes made by Johan Billing 2000-04-16:
- Changed source to use feof() instead of errno == EPASTEOF
- Changed source to use structrw to read and write structures
- Added JAM_AddEmptyMessage()
- Added error messages JAM_NO_MESSAGE and JAM_CORRUPT_MSG for
JAM_ReadMsgHeader()
- #includes stdlib.h instead of malloc.h and memory.h
- Fixed a bug that caused JAM_AddMessage() to fail when trying to
add an empty message to the messagebase under Linux.
Backported changes from JAMLIB 1.4.7 made by Johan Billing 2003-10-26
- Fixed memory leaks that would occur if JAM_ReadMsgHeader() failed
- Added JAM_DeleteMessage()
Other changes made by Johan Billing 2003-10-26
- Fixed comparison between signed and unsigned variable in JAM_AddMessage()
- Improved handling of ActiveMsgs counter. JAM_AddMessage() now only
increases ActiveMsgs if the added message does not have MSG_DELETED set.
JAM_ChangeMsgHeader() decreases ActiveMsgs if MSG_DELETED is set and the
message wasn't already deleted. JAM_DeleteMessage() now only decreases
ActiveMsgs if the message wasn't already deleted.

Changes made by Johan Billing 2000-04-16:
- Fixed broken JAM_GetSubfield()
- #includes stdlib.h instead of malloc.h and memory.h
Changes made by Johan Billing 2000-09-17:
- Added JAM_GetSubfield_R()
Backported changes from JAMLIB 1.4.7 made by Johan Billing 2003-10-22
- JAM_NewSubPacket() and JAM_PutSubField() would give memory leaks under
low memory conditions. Fixed.
Other changes made by Johan Billing 2003-10-22
- Fixed comparison between signed and unsigned variable in
JAM_DelSubPacket() and JAM_GetSubField()
