a64l(3C) AT&T SYSTEM V a64l(3C)
NAME
a64l, l64a - convert between long integer and base-64 ASCII
string
SYNOPSIS
long a64l (s)
char *s;
char *l64a (l)
long l;
DESCRIPTION
These functions are used to maintain numbers stored in
base-64 ASCII characters. 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.
a64l takes a pointer to a null-terminated base-64 represen-
tation and returns a corresponding long value. If the
string pointed to by s contains more than six characters,
a64l will use the first six.
L64a 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.
BUGS
The value returned by l64a is a pointer into a static
buffer, the contents of which are overwritten by each call.
