NAME

a64l, l64a − converts long integer and base-64 ASCII string

LIBRARY

Standard C Library (libc.a)

SYNOPSIS

#include <stdlib.h>

long  a64l (
       const char ∗s);

char ∗l64a (
       long l);

PARAMETERS

sSpecifies a pointer to a character string that is to be converted to a long integer. 

lSpecifies a long integer that is to be converted to a character string. 

DESCRIPTION

The a64l function converts a character string to a long integer.  The l64a function converts a long integer to a character string.  Using these functions provides you the ability to manipulate and store numbers as base-64 ASCII characters. 

Each character used to store a long integer represents a numeric value from 0 through 63.  Up to six characters may be used to represent a long integer.  The characters are translated as follows:

       •A period (.) represents 0. 

       •A slash (/) represents 1. 

       •The numbers 0 through 9 represent 2 through 11. 

       •Uppercase letters A through Z represent 12 through 27. 

       •Lowercase letters a through z represent 38 through 63. 

If the string pointed to by the s parameter exceeds six characters, the a64l function uses only the first six.  A character string is translated from left to right with the least significant number on the left, and each character is translated as a 6-bit radix-64 number. 

If the l parameter is used, the l64a parameter returns a pointer to the corresponding base-64 notation.   If the argument is zero (0), the l64 function returns a pointer to a null string. 

RETURN VALUES

The a64l function returns a long value on success. 

the l64a function returns a pointer to a static buffer whose contents are overwritten with each call.  the contents of
