@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.
