It returns LWRES_R_FAILURE if filename could not be opened or contained incorrect resolver statements. lwres_conf_print() returns LWRES_R_SUCCESS unless an error occurred when converting the network addresses to a numeric host address string. If this happens, the function returns LWRES_R_FAILURE. stdio3 , resolver5 . /etc/resolv.conf
