NAME

       gnutls_certificate_set_x509_trust_file - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

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

ARGUMENTS

       gnutls_certificate_credentials_t            cred
                   is a gnutls_certificate_credentials_t type.

       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().

       This function can also accept URLs. In that case it will import all certificates that  are
       marked   as   trusted.   Note   that   the  supported  URLs  are  the  ones  indicated  by
       gnutls_url_is_supported().

RETURNS

       the number of certificates processed
