API function

## NAME

gnutls\_x509\_crl\_get\_dn\_oid - API function

## SYNOPSIS

**#include \<gnutls/x509.h\>**

**int gnutls\_x509\_crl\_get\_dn\_oid(gnutls\_x509\_crl\_t** *crl***, unsigned** *indx***, void \*** *oid***, size\_t \*** *sizeof\_oid***);**

## ARGUMENTS

- gnutls\_x509\_crl\_t crl

  should contain a gnutls\_x509\_crl\_t type

- unsigned indx

  Specifies which DN OID to send. Use (0) to get the first one.

- void \* oid

  a pointer to store the OID (may be null)

- size\_t \* sizeof\_oid

  initially holds the size of 'oid'

## DESCRIPTION

This function will extract the requested OID of the name of the CRL issuer, specified by the given index.

If oid is null then only the size will be filled.

## RETURNS

**GNUTLS\_E\_SHORT\_MEMORY\_BUFFER** if the provided buffer is not long enough, and in that case the sizeof\_oid will be updated with the required size.  On success 0 is returned.
