OSS Library Calls (i - m) lwres_gethostbyaddr(3)
ERRORS
lwres_gethostbyaddr( ) returns NULL to indicate an error. In this case, the global variable
lwres_h_errno contains one of the following error codes as defined in the netdb.h header file:
HOST_NOT_FOUND
The host or address was not found.
TRY_AGAIN A recoverable error occurred (for example, a timeout). Retrying the lookup
might succeed.
NO_RECOVERY
A nonrecoverable error occurred.
NO_DATA The name exists, but has no address information associated with it (or vice versa
in the case of a reverse lookup). The value NO_ADDRESS is accepted as a
synonym for NO_DATA for backwards compatibility.
