a64l l64a l64a_r - convert between a long integer and a base-64 ASCII string
Lb libc
The characters used to represent ``digits'' are `.' for 0, `/' for 1, `0' - `9' for 2 - 11, `A' - `Z' for 12 - 37, and `a' - `z' for 38 - 63.
The
a64l ();
function takes a pointer to a radix-64 representation, in which the first
digit is the least significant, and returns a corresponding
Vt long
value.
If the string pointed to by
Fa s
contains more than six characters,
a64l ();
uses the first six.
If the first six characters of the string contain a null terminator,
a64l ();
uses only characters preceding the null terminator.
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.
If the type long contains more than 32 bits, the resulting value is
sign-extended.
The behavior of
a64l ();
is unspecified if
Fa s
is a null pointer or the string pointed to by
Fa s
was not generated by a previous call to
l64a (.);
The
l64a ();
function takes a
Vt long
argument and returns a pointer to the corresponding
radix-64 representation.
The behavior of
l64a ();
is unspecified if value is negative.
The value returned by
l64a ();
is a pointer into a static buffer.
Subsequent calls to
l64a ();
may overwrite the buffer.
The
l64a_r ();
function performs a conversion identical to that of
l64a ();
and stores the resulting representation in the memory area pointed to by
Fa buffer ,
consuming at most
Fa buflen
characters including the terminating
NUL
character.
The
l64a ();
function returns a pointer to the radix-64 representation.
If value is 0,
l64a ();
returns a pointer to an empty string.
