I’m afraid the snippet pointed by Ralph is incorrect, as INADDR_ANY should not be a valid return for inet_addr. Here is a quick check on different OSes.
On Linux, the man Page states: > If the input is invalid, INADDR_NONE (usually -1) is returned. On Mac OS X: > The constant INADDR_NONE is returned by inet_addr() and inet_network() for > malformed requests. On Windows things are slightly more complicated: > On Windows Server 2003 and later if the string in the cp parameter is an > empty string, then inet_addr returns the value INADDR_NONE.

If NULL is passed in the > cp parameter, then inet_addr returns the value INADDR_NONE. Thus, we should compare with INADDR_NONE and not with INADDR_ANY. George.
