a64l(3C) — A/UX 3.0.1




a64l(3C)                                                 a64l(3C)



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

SYNOPSIS
     long a64l(s)
     char *s;

     char *l64a(l)
     long l;

DESCRIPTION
     These functions are used to maintain numbers stored in
     base-64 ASCII characters.  This is a notation by which long
     integers can be represented by up to 6 characters; each
     character represents a ``digit'' in a radix-64 notation.

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

     a64l 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 6 characters,
     uses the first 6.

     l64a 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.

LIMITATIONS
     The value returned by l64a is a pointer into a static
     buffer, the contents of which are overwritten by each call.
