+The function returns a pointer to a static buffer which contains the

+bytes the use should append the new string to the destination buffer.

+To decode data produced with @code{l64a} the following function should be
+used.
+
+@deftypefun {long int} a64l (const char *@var{string})
+The parameter @var{string} should contain a string which was produced by
+a call to @code{l64a}.  The function processes the next 6 characters and
+decodes the characters it finds according to the table above.
+Characters not in the conversion table are simply ignored.  This is
+useful for breaking the information in lines in which case the end of
+line characters are simply ignored.
+
+The decoded number is returned at the end as a @code{long int} value.
+Consecutive calls to this function are possible but the caller must make
+sure the buffer pointer is update after each call to @code{a64l} since
+this function does not modify the buffer pointer.  Every call consumes 6
+characters.
