# gnutls\_ocsp\_status\_request\_enable\_client(3)

API function

## NAME

gnutls\_ocsp\_status\_request\_enable\_client - API function

## SYNOPSIS

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

**int gnutls\_ocsp\_status\_request\_enable\_client(gnutls\_session\_t** *session***, gnutls\_datum\_t \*** *responder\_id***, size\_t** *responder\_id\_size***, gnutls\_datum\_t \*** *extensions***);**

## ARGUMENTS

- gnutls\_session\_t session

  is a **gnutls\_session\_t** type.

- gnutls\_datum\_t \* responder\_id

  ignored, must be **NULL**

- size\_t responder\_id\_size

  ignored, must be zero

- gnutls\_datum\_t \* extensions

## 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

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

## SINCE

3\.1.3
