== NAME

nng_tls_config_server_name - configure remote server name

== SYNOPSIS

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

int nng_tls_config_server_name(nni_tls_config *cfg, const char *name);
-----------

== DESCRIPTION

The `nng_tls_config_server_name()` function configures the remote server name
to be used by a client when connection to a server.  The supplied 'name'
is used when comparing the identity in the server's certificate.  Furthermore,
when Server Name Indication (SNI) is used, the 'name' may be sent to the server
as a hint to tell it which of several possible certificates should be used.

TIP: This function is only useful in configuring client behavior.

== RETURN VALUES

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

== ERRORS

`NNG_ENOMEM`:: Insufficient memory is available.
`NNG_EBUSY`:: The configuration 'cfg' is already in use, and cannot be modified.
