# gnutls\_certificate\_set\_ocsp\_status\_request\_function(3)

API function

## NAME

gnutls\_certificate\_set\_ocsp\_status\_request\_function - API function

## SYNOPSIS

**#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

- gnutls\_certificate\_credentials\_t sc

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

- gnutls\_status\_request\_ocsp\_func ocsp\_func

  function pointer to OCSP status request callback.

- void \* ptr

  opaque pointer passed to callback function

## 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()**.
