.SH DESCRIPTION
The
.IR http_cookie_create ()
function allocates a null-terminated string with a HTTP/1.1 cookie
defined by
.I key
and
.IR value ,
which are null-terminated strings, with an optional expiration date defined by
.IR exp .

If
.I exp
is a null pointer, no expiration date is set to the cookie, and therefore it
effectively acts as a session cookie.

.SH RETURN VALUE
On success, a null-terminated string with the newly HTTP/1.1 cookie is
returned. Otherwise, a null pointer is returned.

.SH ERRORS
No errors are defined.

.SH EXAMPLE
A successful call to
.IR http_cookie_create (3)
with

as
.I value
and

pointing to a given calendar time
might return a null-terminated string such as the one below:
