== NAME

nng_http_client_set_tls - set HTTP client TLS configuration

== SYNOPSIS

[source, c]
-----------
#include <nng/nng.h>
#include <nng/supplemental/http/http.h>

int nng_http_client_set_tls(nng_http_client *client, nng_tls_config *cfg);
-----------

== DESCRIPTION

The `nng_http_client_set_tls()` sets the TLS configuration of _client_ to _cfg_.

This change overwrites any previous TLS configuration.

IMPORTANT: This also invalidates any previously obtained values from
`<<nng_http_client_get_tls.3http#,nng_http_client_get_tls()>>`.

NOTE: Any connections established with
`<<nng_http_client_connect.3http#,nng_http_client_connect()>>`
will continue to use any TLS configuration that they were started with.

== RETURN VALUES

This function returns 0 on success, and non-zero otherwise.

== ERRORS

`NNG_ENOMEM`:: Insufficient free memory exists.
`NNG_ENOTSUP`:: Either HTTP or TLS not supported.
