NAME

     a64l, l64a, l64a_r -- convert between a long integer and a base-64 ASCII string

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <stdlib.h>

     long
     a64l(const char *s);

     char *
     l64a(long int l);

     int
     l64a_r(long int l, char *buffer, int buflen);

DESCRIPTION

     The a64l() and l64a() functions convert between a long integer and its base-64 ASCII string representation.

     The characters used to represent ``digits'' are `.' for 0, `/' for 1, `0' - `9' for 2 - 11, `A' - `Z' for 12 - 37, and `a' - `z' for 38 - 63.

     a64l() takes a pointer to a NUL-terminated base-64 ASCII string representation, s, and returns the corresponding long integer value.

     l64a() takes a long integer value, l, and returns a pointer to the corresponding NUL-terminated base-64 ASCII string representation.

     l64a_r() performs a conversion identical to that of l64a() and stores the resulting representation in the memory area pointed to by buffer,
     consuming at most buflen characters including the terminating NUL character.

RETURN VALUES

     On successful completion, a64l() returns the long integer value corresponding to the input string.  If the string pointed to by s is an empty
     string, a64l() returns a value of 0L.

     l64a() returns a pointer to the base-64 ASCII string representation corresponding to the input value.  If l is 0L, l64a() returns a pointer
     to an empty string.

     On successful completion, l64a_r() returns 0; if buffer is of insufficient length, -1 is returned.

SEE ALSO

     strtol(3)

STANDARDS

     The a64l() and l64a() functions conform to X/Open Portability Guide Issue 4, Version 2 (``XPG4.2'') and IEEE Std 1003.1-2004 (``POSIX.1'').
     The l64a_r() function conforms to System V Interface Definition, Fourth Edition (``SVID4''), Multithreading Extension.

BUGS

     The l64a() function is not reentrant.  The value returned by it points into a static buffer area; subsequent calls to la64a() may overwrite
     this buffer.  In multi-threaded applications, l64a_r() should be used instead.
