NAME         top

       gnutls_pkcs11_get_raw_issuer_by_dn - API function

SYNOPSIS         top

       #include <gnutls/pkcs11.h>

       int gnutls_pkcs11_get_raw_issuer_by_dn(const char * url, const
       gnutls_datum_t * dn, gnutls_datum_t * issuer,
       gnutls_x509_crt_fmt_t fmt, unsigned int flags);

ARGUMENTS         top

       const char * url
                   A PKCS 11 url identifying a token

       const gnutls_datum_t * dn
                   is the DN to search for

       gnutls_datum_t * issuer
                   Will hold the issuer if any in an allocated buffer.

       gnutls_x509_crt_fmt_t fmt
                   The format of the exported issuer.

       unsigned int flags
                   Use zero or flags from GNUTLS_PKCS11_OBJ_FLAG.

DESCRIPTION         top

       This function will return the certificate with the given DN, if it
       is stored in the token. By default only marked as trusted issuers
       are returned. If any issuer should be returned specify
       GNUTLS_PKCS11_OBJ_FLAG_RETRIEVE_ANY in  flags .

       The name of the function includes issuer because it can be used to
       discover issuers of certificates.

RETURNS         top

       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative
       error value.

SINCE         top
