nng_tls_config_server_name - configure remote server name

#include <nng/nng.h>
#include <nng/supplemental/tls/tls.h>
int nng_tls_config_server_name(nng_tls_config *cfg, const char *name);

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.

This function is only useful in configuring client behavior.

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