"Bad" in what sense?
If it's null, the open failed - but the current SVN version of
Wireshark, at least, checks for that, and just gives up.
Exactly! Here's the bit from addr_resolve.c that fails:
if ((hf = eth_fopen(hostspath, "r")) == NULL)
return
FALSE;
while (fgetline(&line, &size, hf) >= 0) {
According to MSVC, the value of "hf" returned by eth_fopen is:
hf 0x77c5fce0 {_ptr=0x00000000 <Bad Ptr> _cnt=0 _base=0x00000000 <Bad Ptr> ...} _iobuf *
So "bad" in the "Bad Ptr" sense. It's not "NULL" otherwise I would never have hit the fgetline.
Any thoughts appreciated.
