NAME         top

       gnutls_server_name_set - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       int gnutls_server_name_set(gnutls_session_t session,
       gnutls_server_name_type_t type, const void * name, size_t

ARGUMENTS         top

       gnutls_session_t session
                   is a gnutls_session_t type.

       gnutls_server_name_type_t type
                   specifies the indicator type

       const void * name
                   is a string that contains the server name.

       size_t name_length
                   holds the length of name excluding the terminating
                   null byte

DESCRIPTION         top

       This function is to be used by clients that want to inform (via a
       TLS extension mechanism) the server of the name they connected
       to.  This should be used by clients that connect to servers that
       do virtual hosting.

       The value of  name depends on the  type type.  In case of
       GNUTLS_NAME_DNS, a UTF-8 null-terminated domain name string,
       without the trailing dot, is expected.

       IPv4 or IPv6 addresses are not permitted to be set by this
       function.  If the function is called with a name of  name_length
       zero it will clear all server names set.

RETURNS         top

       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a
       negative error code is returned.
