Use (0) to get the first one. .IP "void * oid" 12 a pointer to a structure to hold the OID .IP "size_t * sizeof_oid" 12 initially holds the maximum size of \fIoid\fP , on return holds actual size of \fIoid\fP . .SH "DESCRIPTION" This function will return the requested attribute OID in the certificate, and the critical flag for it. The attribute OID will be stored as a string in the provided buffer. Use \fBgnutls_x509_crq_get_attribute_data()\fP to extract the data. If the buffer provided is not long enough to hold the output, then * \fIsizeof_oid\fP is updated and \fBGNUTLS_E_SHORT_MEMORY_BUFFER\fP will be returned. .SH "RETURNS" On success, \fBGNUTLS_E_SUCCESS\fP (0) is returned, otherwise a negative error code in case of an error. If your have reached the last extension available \fBGNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE\fP will be returned. .SH "SINCE" 2.8.0 .SH "REPORTING BUGS" Report bugs to . .br Home page: https://www.gnutls.org .SH COPYRIGHT Copyright \(co 2001-2021 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.
