#include <lwres/netdb.h>
void
lwres_herror(const char *s);
const char *
lwres_hstrerror(int err);
lwres_herror() prints the string
s on stderr followed by the string
generated by lwres_hstrerror() for the error code
stored in the global variable lwres_h_errno.
lwres_hstrerror() returns an appropriate string
for the error code gievn by err. The values of
the error codes and messages are as follows:
