A64L(3C)        DOMAIN/IX Reference Manual (SYS5)        A64L(3C)



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

USAGE
     long a64l (s)
     char *s;

     char *l64a (l)
     long l;

DESCRIPTION
     These functions maintain numbers stored in base-64 ASCII
     characters.  Long integers can be represented by up to six
     characters; each character represents one ``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 represen-
     tation and returns a corresponding long value.  If the
     string that s points to contains more than six characters,
     a64l will interpret the first six only.

     L64a takes a long argument and returns a pointer to the
     corresponding base-64 representation.  If the argument is
     zero, l64a returns a pointer to a null string.

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