## DESCRIPTION

`lwres_conf_init()` creates an empty lwres_conf_t structure for lightweight resolver context ctx.

`lwres_conf_clear()` frees up all the internal memory used by that lwres_conf_t structure in resolver context ctx.

`lwres_conf_parse()` opens the file filename and parses it to initialise the resolver context ctx's lwres_conf_t structure.

`lwres_conf_print()` prints the lwres_conf_t structure for resolver context ctx to the FILE fp.

## RETURN VALUES

`lwres_conf_parse()` returns LWRES_R_SUCCESS if it successfully read and parsed filename. 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.
