a64l(3C)						   Standard C Library Functions 						  a64l(3C)

NAME

       a64l, l64a - convert between long integer and base-64 ASCII string

SYNOPSIS

       #include <stdlib.h>

       long a64l(const char *s);

       char *l64a(long l);

DESCRIPTION

       These  functions maintain numbers stored in base-64 ASCII characters that define a notation by which long integers can be represented by up
       to six characters. Each character represents a "digit" in a radix-64 notation.

       The characters used to represent "digits" are as follows:

       +-----------------------------+--------------------------------+
       |	 Character	     |		 Digit		      |
       |	     .		     |		   0		      |
       |	     /		     |		   1		      |
       |	    0-9 	     |		  2-11		      |
       |	    A-Z 	     |		 12-37		      |
       |	    a-z 	     |		 38-63		      |
       +-----------------------------+--------------------------------+

       The a64l() function takes a pointer to a null-terminated base-64 representation and returns a corresponding  long  value.   If  the  string
       pointed to by s contains more than six characters, a64l() uses the first six.

       The  a64l() function scans the character string from left to right with the least significant digit on the left, decoding each character as
       a 6-bit radix-64 number.

       The l64a() function takes a long argument and returns a pointer to the corresponding base-64 representation. If the argument is	0,  l64a()
       returns a pointer to a null string.

       The  value returned by l64a() is a pointer into a static buffer, the contents of which are overwritten by each call.  In the case of multi-
       threaded applications, the return value is a pointer to thread specific data.
