lwres_config(3)

NAME

       lwres_conf_init, lwres_conf_clear, lwres_conf_parse, lwres_conf_print,
       lwres_conf_get - lightweight resolver configuration

SYNOPSIS

       #include <lwres/lwres.h>

       void lwres_conf_init(lwres_context_t *ctx);

       void lwres_conf_clear(lwres_context_t *ctx);

       lwres_result_t lwres_conf_parse(lwres_context_t *ctx,
                                       const char *filename);

       lwres_result_t lwres_conf_print(lwres_context_t *ctx, FILE *fp);

       lwres_conf_t * lwres_conf_get(lwres_context_t *ctx);

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 FILEfp.

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.
