**#include <gnutls/gnutls.h>**

**void gnutls\_certificate\_set\_ocsp\_status\_request\_function(gnutls\_certificate\_credentials\_t sc, gnutls\_status\_request\_ocsp\_func ocsp\_func, void * ptr);**

# [ARGUMENTS](#ARGUMENTS)

[gnutls\_certificate\_credentials\_t sc](#gnutls_certificate_credentials_t)

is a **gnutls\_certificate\_credentials\_t** type.

[gnutls\_status\_request\_ocsp\_func ocsp\_func](#gnutls_status_request_ocsp_func)

function pointer to OCSP status request callback.

[void * ptr](#void)

opaque pointer passed to callback function

# [DESCRIPTION](#DESCRIPTION)

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 **GNUTLS\_E\_NO\_CERTIFICATE\_STATUS**, if there is no recent OCSP response. If the callback returns **GNUTLS\_E\_SUCCESS**, it is expected to have the *ocsp\_response* field set with a valid (DER-encoded) OCSP response. The response must be a value allocated using **gnutls\_malloc()**, and will be deinitialized by the caller.

It is possible to set a specific callback for each provided certificate using **gnutls\_certificate\_set\_ocsp\_status\_request\_function2()**.
