RedHat 9 (Linux i386) - man page for a64l (redhat section 3)

A64L(3) 			    Linux Programmer's Manual				  A64L(3)

NAME
       a64l, l64a - convert between long and base-64

SYNOPSIS
       #include <stdlib.h>

       long a64l(char *str64);

       char *l64a(long value);

DESCRIPTION
       These  functions  provide  a  conversion  between  32-bit  long integers and little-endian
       base-64 ASCII strings (of length zero to six).  If the string used as argument for  a64l()
       has  length  greater than six, only the first six bytes are used.  If longs have more than
       32 bits, then l64a() uses only the low order 32 bits of value, and a64l() sign-extends its
       32-bit result.

       The 64 digits in the base 64 system are:
	      '.'  represents a 0
	      '/'  represents a 1
	      0-9  represent  2-11
	      A-Z  represent 12-37
	      a-z  represent 38-63
       So 123 = 59*64^0 + 1*64^1 = "v/".

NOTES
       The  value returned by a64l() may be a pointer to a static buffer, possibly overwritten by
       later calls.

       The behaviour of l64a() is undefined when value is negative. If value is zero, it  returns
       an empty string.

       These functions are broken in glibc before 2.2.5 (puts most significant digit first).

CONFORMING TO
       XPG 4.2, POSIX 1003.1-2001.
