#include <search.h>
[...]
struct hsearch_data htab_ports;
[...]
memset (&htab_ports, 0, sizeof (struct hsearch_data));


gives errors:

snif.c:153: error: storage size of `htab_ports' isn't known
[...]
snif.c:2057: error: invalid application of `sizeof' to an incomplete type


any help will be greatly appreciated

Non-standard header.

<OT> Try #define _GNU_SOURCE like it says on the manpage. </OT>

<search.h> isn't a standard C header file, so it's hard to say what
is going wrong beside that obviously "struct htsearch_data" isn't
defined anywhere where the compiler can find it.

<OT>
If you're compiling this under some kind of Linux you may have
to #define _GNU_SOURCE to get the compiler to see what that
structure is. Send further question to comp.unix.programmer
in that case, please.
