NAME

       gnutls_x509_trust_list_get_issuer - API function

SYNOPSIS

       #include <gnutls/x509.h>

       int   gnutls_x509_trust_list_get_issuer(gnutls_x509_trust_list_t  list,  gnutls_x509_crt_t
       cert, gnutls_x509_crt_t * issuer, unsigned int flags);

ARGUMENTS

       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. Should be treated as constant.

       unsigned int flags
                   Use zero or GNUTLS_TL_GET_COPY

DESCRIPTION

       This  function  will  find  the  issuer  of  the   given   certificate.    If   the   flag
       GNUTLS_TL_GET_COPY  is specified a copy of the issuer will be returned which must be freed
       using gnutls_x509_crt_deinit().  Note that the flag  GNUTLS_TL_GET_COPY  is  required  for
       this function to work with PKCS 11 trust lists in a thread-safe way.

RETURNS

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

SINCE
