#include <gnutls/x509.h>

ARGUMENTS

gnutls_x509_crt_t cert

void * oid

a pointer to a buffer to hold the OID (may be null)

size_t * oid_size

initially holds the size of oid

DESCRIPTION

This function will extract the OIDs of the name of the Certificate issuer specified by the given index.

If oid is null then only the size will be filled. The oid returned will be null terminated, although oid_size will not account for the trailing null.
