.fi
.SH DESCRIPTION
The
.IR form_alloc (3)
function parses a
.I application/x-www-form-urlencoded
human-readable string from
.I data
and, if successful, allocates a
.I struct form
instance into
.IR f ,
which can then be used by other functions from this library.
.SH RETURN VALUE
On success, zero is returned and
.I f
is initialized to a valid pointer.
If
.I data
contains invalid data,
a positive integer is returned and
.I f
is not modified.
On fatal errors (e.g.: a failed memory allocation),
a negative integer is returned and
.I f
is not modified.
.SH EXAMPLE
See
.IR libweb_form (7)
for a complete example on how to use this library.
