It returns LWRES_R_FAILURE if \fIfilename\fR could not be opened or contained incorrect resolver statements. .PP \fBlwres_conf_print()\fR 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. .SH "SEE ALSO" .PP \fBstdio\fR(3), \fBresolver\fR(5). .SH "FILES" .PP \fI/etc/resolv.conf\fR
