gnutls_certificate_set_x509_trust_file - API function
#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);
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
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 PKCS 11 URLs. In that case it will import all certificates that are marked as trusted.
number of certificates processed, or a negative value on error.
