If \fIoid\fP is null then only the size will be filled. The \fIoid\fP returned will be null terminated, although \fIoid_size\fP will not account for the trailing null. This function is only useful if \fBgnutls_x509_crt_get_issuer_alt_name()\fP returned \fBGNUTLS_SAN_OTHERNAME\fP. .SH "RETURNS" the alternative issuer name type on success, one of the enumerated gnutls_x509_subject_alt_name_t. For supported OIDs, it will return one of the virtual (GNUTLS_SAN_OTHERNAME_*) types, e.g. \fBGNUTLS_SAN_OTHERNAME_XMPP\fP, and \fBGNUTLS_SAN_OTHERNAME\fP for unknown OIDs. It will return \fBGNUTLS_E_SHORT_MEMORY_BUFFER\fP if \fIret_size\fP is not large enough to hold the value. In that case \fIret_size\fP will be updated with the required size. If the certificate does not have an Alternative name with the specified sequence number and with the otherName type then \fBGNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE\fP is returned. .SH "SINCE" 2.10.0 .SH "REPORTING BUGS" Report bugs to . .br Home page: https://www.gnutls.org .SH COPYRIGHT Copyright \(co 2001-2023 Free Software Foundation, Inc., and others. .br 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. .SH "SEE ALSO" The full documentation for .B gnutls is maintained as a Texinfo manual.
