# gnutls\_ocsp\_resp\_get\_certs(3)

API function

## NAME

gnutls\_ocsp\_resp\_get\_certs - API function

## SYNOPSIS

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

**int gnutls\_ocsp\_resp\_get\_certs(gnutls\_ocsp\_resp\_const\_t** *resp***, gnutls\_x509\_crt\_t \*\*** *certs***, size\_t \*** *ncerts***);**

## ARGUMENTS

- gnutls\_ocsp\_resp\_const\_t resp

  should contain a **gnutls\_ocsp\_resp\_t** type

- gnutls\_x509\_crt\_t \*\* certs

  newly allocated array with **gnutls\_x509\_crt\_t** certificates

- size\_t \* ncerts

  output variable with number of allocated certs.

## DESCRIPTION

This function will extract the X.509 certificates found in the Basic OCSP Response.  The  *certs* output variable will hold a newly allocated zero-terminated array with X.509 certificates.

Every certificate in the array needs to be de-allocated with **gnutls\_x509\_crt\_deinit()** and the array itself must be freed using **gnutls\_free()**.

Both the  *certs* and  *ncerts* variables may be NULL.  Then the function will work as normal but will not return the NULL:d information.  This can be used to get the number of certificates only, or to just get the certificate array without its size.

## RETURNS

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