int gnutls_x509_name_constraints_get_permitted(gnutls_x509_name_constraints_t nc, unsigned idx, unsigned * type, gnutls_datum_t * name);
- gnutls_x509_name_constraints_t nc
- the extracted name constraints
- unsigned idx
- the index of the constraint
- unsigned * type
- the type of the constraint (of type gnutls_x509_subject_alt_name_t)
- gnutls_datum_t * name
- the name in the constraint (of the specific type)
DESCRIPTIONThis function will return an intermediate type containing the name constraints of the provided CA certificate. That structure can be used in combination with gnutls_x509_name_constraints_check() to verify whether a server's name is in accordance with the constraints.
The name should be treated as constant and valid for the lifetime of nc .
RETURNSOn success, GNUTLS_E_SUCCESS (0) is returned, GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE if the extension is not present, otherwise a negative error value.
