Re: Network programming
Hi,
I have some hint for you. You have a C function called the gethostbyname and gethostbyaddr. I think this should solve your problem. else you can also try "resolver", but i guess "resolver" is linux specific.

lwres_conf_get
LWRES_CONFIG(3) BIND9 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 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.
