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 On success, **GNUTLS\_E\_SUCCESS** (0) is returned, otherwise a negative error code is returned. ## REPORTING BUGS Report bugs to \.\ Home page: https://www.gnutls.org ## COPYRIGHT Copyright © 2001-2023 Free Software Foundation, Inc., and others.\ Copying and distribution of this file, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved. ## SEE ALSO The full documentation for **gnutls** is maintained as a Texinfo manual.
