== NAME
nng_http_server_add_handler - add HTTP server handler
== SYNOPSIS
[source, c]
----
#include <nng/nng.h>
#include <nng/supplemental/http/http.h>
int nng_http_server_add_handler(nng_http_server *s, nng_http_handler *h);
----
== DESCRIPTION
The `nng_http_server_add_handler()` adds the handler _h_ to the server
instance _s_.
If another handler is already added to the server that would conflict
with handler _h_, then the operation will fail with `NNG_EADDRINUSE`.
If a handler is added to a server, and the server is subsequently
deallocated, the handler and any of its resources will also be deallocated.
Handlers that are added to a server may be subsequently removed using the
<<nng_http_server_del_handler.3http#,`nng_http_server_del_handler()`>> function.
== RETURN VALUES
This function returns 0 on success, and non-zero otherwise.
== ERRORS
`NNG_EADDRINUSE`:: Handler conflicts with another handler.
`NNG_ENOMEM`:: Insufficient free memory exists.
`NNG_ENOTSUP`:: HTTP not supported.
