A64L(3C)            UNIX Programmer's Manual             A64L(3C)

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

SYNOPSIS
     long a64l (s)
     char *s;

     char *l64a (l)
     long l;

HP-UX COMPATIBILITY
     Level:    HP-UX/RUN ONLY

DESCRIPTION
     These routines are used to maintain numbers stored in  _b_a_s_e-
     _6_4  ASCII.  This is 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 . for 0, / for
     1,  0  through  9  for  2-11,  A  through Z for 12-37, and a
     through z for 38-63.

     The leftmost character is the least most significant  digit.
     For example,

          a0 = (38 x 64^0) + (2 x 64^1) = 166

     _A_6_4_l takes a pointer to a null-terminated base-64  represen-
     tation and returns a corresponding long value.  _L_6_4_a takes a
     long argument and returns a  pointer  to  the  corresponding
     base-64 representation.

BUGS
     The value returned by  _l_6_4_a  is  a  pointer  into  a  static
     buffer, the contents of which are overwritten by each call.
