== 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
|
|
xref:nng_http_server_del_handler.3http.adoc[`nng_http_server_del_handler()`] function.
|
|
|
|
== RETURN VALUES
|
|
|
|
This function returns 0 on success, and non-zero otherwise.
|
|
|
|
== ERRORS
|
|
|
|
[horizontal]
|
|
`NNG_EADDRINUSE`:: Handler conflicts with another handler.
|
|
`NNG_ENOMEM`:: Insufficient free memory exists.
