#include <gnutls/x509.h>int gnutls_x509_trust_list_get_issuer(gnutls_x509_trust_list_tlist, gnutls_x509_crt_tcert, gnutls_x509_crt_t *issuer, unsignedintflags);

ARGUMENTS        top

       gnutls_x509_trust_list_t list                   The list       gnutls_x509_crt_t cert                   is the certificate to find issuer for       gnutls_x509_crt_t * issuer                   Will hold the issuer if any.

In that case the providedissuer must not be initialized.       Note that the flagGNUTLS_TL_GET_COPYis required for this       function to work with PKCS11trust lists in a thread-safe way.
