NAME

       gnutls_certificate_set_x509_trust_file  -  Used to add trusted CAs in a
       gnutls_certificate_credentials_t structure

SYNOPSIS

       #include <gnutls/gnutls.h>

       int
       gnutls_certificate_set_x509_trust_file(gnutls_certificate_credentials_t
       res, const char * cafile, gnutls_x509_crt_fmt_t type);

ARGUMENTS

       gnutls_certificate_credentials_t res
                   is a gnutls_certificate_credentials_t structure.

       const char * cafile
                   is a file containing the list of trusted CAs  (DER  or  PEM
                   list)

       gnutls_x509_crt_fmt_t type
                   is PEM or DER

DESCRIPTION

       This  function adds the trusted CAs in order to verify client or server
       certificates. In case of a client this is not required to be called  if
       the        certificates        are       not       verified       using
       gnutls_certificate_verify_peers2().   This  function  may   be   called
       multiple times.

       In  case  of a server the names of the CAs set here will be sent to the
       client if a certificate request is sent. This  can  be  disabled  using
       gnutls_certificate_send_x509_rdn_sequence().

RETURNS

       number of certificates processed, or a negative value on error.
