Use zero to get the first one. void * oid a pointer to a structure to hold the OID size_t * sizeof_oid initially holds the maximum size of oid, on return holds actual size of oid. int * critical output variable with critical flag, may be NULL.DESCRIPTIONThis function will return the requested extension OID in the certificate, and the critical flag for it. The extension OID will be stored as a string in the provided buffer. Use gnutls_x509_crt_get_extension_data() to extract the data. If the buffer provided is not long enough to hold the output, then *sizeof_oid is updated and GNUTLS_E_SHORT_MEMORY_BUFFER will be returned.RETURNSOn success, GNUTLS_E_SUCCESS (zero) is returned, otherwise an error code is returned.
