@deftypefun {int} {gnutls_certificate_set_x509_trust_dir} (gnutls_certificate_credentials_t @var{cred}, const char * @var{ca_dir}, gnutls_x509_crt_fmt_t @var{type})
@var{cred}: is a @code{gnutls_certificate_credentials_t}  type.

@var{ca_dir}: is a directory containing the list of trusted CAs (DER or PEM list)

@var{type}: is PEM or DER

This function adds the trusted CAs present in the directory in order to
verify client or server certificates. This function is identical
to @code{gnutls_certificate_set_x509_trust_file()}  but loads all certificates
in a directory.

@strong{Returns:} the number of certificates processed

@strong{Since:} 3.3.6
