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

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.
