== NAME
nng_http_handler_set_method - set HTTP handler method
== SYNOPSIS
[source, c]
----
#include <nng/nng.h>
#include <nng/supplemental/http/http.h>
int nng_http_handler_set_method(nng_http_handler *handler, const char *method);
----
== DESCRIPTION
The `nng_http_handler_set_method()` function sets the _method_ that the
_handler_ will be called for, such as "GET" or "POST".
(By default the "GET" method is handled.)
If _method_ is `NULL`, then the request method
is not examined, and the handler will be executed regardless of the
method.
NOTE: The server will automatically call "GET" handlers if the client
sends a "HEAD" request, and will suppress HTTP body data in the responses
sent for such requests.
NOTE: No validation of the _method_ is performed, but HTTP specifications
insist that the actual method sent over the wire be capitalized.
The handler may always examine the actual method used using the
`<<nng_http_req_get_method.3http#,nng_http_req_get_method()>>` function.
== RETURN VALUES
This function returns 0 on success, and non-zero otherwise.
== ERRORS
`NNG_ENOMEM`:: Insufficient free memory exists.
`NNG_ENOTSUP`:: No support for HTTP in the library.
