.SH NAME
JAM_Crc32 \- Calculate CRC32 on a block of data
.SH SYNOPSIS
.nf
.B #include <jamlib/jam.h>

.BI "ulong JAM_Crc32(uchar* " Buffer_PC ","
.BI "                ulong  " Length_I ");"
.RE
.fi
.SH DESCRIPTION
Calculates the Crc32 value for a block of data. All ASCII 
characters are converted to lowercase before calculating
the CRC (the input data is unchanged).
.SS Arguments
.TP
.I Buffer_PC
A pointer to the first byte of the data block
.TP
.I Length_I
The number of bytes in the data block
.SH "RETURN VALUE"
The Crc32 value
.SH EXAMPLES
.nf
ulong Crc_I;
uchar Text_AC[32];

strcpy(Text_AC, "Hello world!\\n");

Crc_I = JAM_Crc32(Text_AC, strlen(Text_AC));
