@deftypefun {void} {gnutls_certificate_set_ocsp_status_request_function} (gnutls_certificate_credentials_t @var{sc}, gnutls_status_request_ocsp_func @var{ocsp_func}, void * @var{ptr})
@var{sc}: is a @code{gnutls_certificate_credentials_t}  type.

@var{ocsp_func}: function pointer to OCSP status request callback.

@var{ptr}: opaque pointer passed to callback function

This function is to be used by server to register a callback to
handle OCSP status requests from the client.  The callback will be
invoked if the client supplied a status-request OCSP extension.
The callback function prototype is:

typedef int (*gnutls_status_request_ocsp_func)
(gnutls_session_t session, void *ptr, gnutls_datum_t *ocsp_response);

The callback will be invoked if the client requests an OCSP certificate
status.  The callback may return @code{GNUTLS_E_NO_CERTIFICATE_STATUS} , if
there is no recent OCSP response. If the callback returns @code{GNUTLS_E_SUCCESS} ,
the server will provide the client with the ocsp_response.

The response must be a value allocated using @code{gnutls_malloc()} , and will be
deinitialized when needed.

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned,
otherwise a negative error code is returned.

@strong{Since:} 3.1.3
