@var{url}: A PKCS 11 url identifying a token
@var{cert}: is the certificate to find issuer for
@var{issuer}: Will hold the issuer if any in an allocated buffer.
@var{fmt}: The format of the exported issuer.
@var{flags}: Use zero or flags from @code{GNUTLS_PKCS11_OBJ_FLAG} .
This function will return the issuer of a given certificate, if it
is stored in the token. By default only marked as trusted issuers
are returned. If any issuer should be returned specify
@code{GNUTLS_PKCS11_OBJ_FLAG_RETRIEVE_ANY} in @code{flags} .
@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS} (0) is returned, otherwise a
negative error value.
@strong{Since:} 3.2.7
