Use zero to get the first one. void * data a pointer to a structure to hold the data (may be null) size_t * sizeof_data initially holds the size of oidDESCRIPTIONThis function will return the requested extension data in the certificate. The extension data will be stored as a string in the provided buffer. Use gnutls_x509_crt_get_extension_info() to extract the OID and critical flag. Use gnutls_x509_crt_get_extension_by_oid() instead, if you want to get data indexed by the extension OID rather than sequence.RETURNSOn success, GNUTLS_E_SUCCESS (zero) is returned, otherwise an error code is returned. If you have reached the last extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.REPORTING BUGSReport bugs to <bug-gnutls@gnu.org>.
