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

       #include <stdlib.h>

       long a64l(const char *s);

       char *l64a(long l);

       These  functions	 maintain  numbers  stored in base-64 ASCII characters
       that define a notation by which long integers can be represented by  up
       to  six	characters.  Each character represents a "digit" in a radix-64

       The characters used to represent "digits" are as follows:

       │Character │ Digit │
       │.	  │ 0	  │
       │/	  │ 1	  │
       │0-9	  │ 2-11  │
       │A-Z	  │ 12-37 │
       │a-z	  │ 38-63 │

       The a64l() function takes a pointer to a null-terminated base-64 repre‐
       sentation  and  returns	a  corresponding  long	value.	 If the string
       pointed to by s contains more than  six	characters,  a64l()  uses  the
       first six.

       The  a64l() function scans the character string from left to right with
       the least significant digit on the left, decoding each character	 as  a
       6-bit radix-64 number.

       The  l64a() function 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.

       The  value  returned  by	 l64a() is a pointer into a static buffer, the
       contents of which are overwritten by each call.	In the case of	multi‐
       threaded applications, the return value is a pointer to thread specific
