lwres_herror, lwres_hstrerror - lightweight resolver error message generation #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:

NETDB_SUCCESS Resolver Error 0 (no error)

HOST_NOT_FOUND Unknown host

TRY_AGAIN Host name lookup failure

NO_RECOVERY Unknown server error

NO_DATA No address associated with name

The string Unknown resolver error is returned by lwres_hstrerror() when the value of lwres_h_errno is not a valid error code.
