gnutls_ocsp_req_get_extension - API function
int gnutls_ocsp_req_get_extension(gnutls_ocsp_req_t req, unsigned indx, gnutls_datum_t * oid, unsigned int * critical, gnutls_datum_t * data);
- gnutls_ocsp_req_t req
should contain a gnutls_ocsp_req_t type
- unsigned indx
Specifies which extension OID to get. Use (0) to get the first one.
- gnutls_datum_t * oid
will hold newly allocated buffer with OID of extension, may be NULL
- unsigned int * critical
output variable with critical flag, may be NULL.
- gnutls_datum_t * data
will hold newly allocated buffer with extension data, may be NULL
This function will return all information about the requested
extension in the OCSP request. The information returned is the
OID, the critical flag, and the data itself. The extension OID
will be stored as a string. Any of oid
, and data
be NULL which means that the caller is not interested in getting
that information back.
The caller needs to deallocate memory by calling gnutls_free() on
oid ->data and data ->data.
On success, GNUTLS_E_SUCCESS
(0) is returned, otherwise a
negative error code is returned. If you have reached the last
extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE
