# [DESCRIPTION](#DESCRIPTION)

This function is to be used by clients to request OCSP response from the server, using the "status\_request" TLS extension. Only OCSP status type is supported.

Previous versions of GnuTLS supported setting *responder\_id* and  
*extensions* fields, but due to the difficult semantics of the parameter usage, and other issues, this support was removed since 3.6.0 and these parameters must be set to **NULL**.

# [RETURNS](#RETURNS)

On success, **GNUTLS\_E\_SUCCESS** (0) is returned, otherwise a negative error code is returned.
