Wireshark-users: Re: [Wireshark-users] Getting response values from wireshark ??

Hi,

The problem is that pclose returns 0 in either case. 
I've tried it with fork + execl too and there it's the same. The result
of execl is a negative number whether wireshark has started correctly or
not.
The return code of pclose or execl does not reflect whether wireshark
was able to start correctly (with valid parameters).

Hi,

Wireshark has no option to suppress it's output. You could play with the
way you popen(), but I'm not familiar what Solaris provides in this
respect.
pclose() should provide you with the exit status of Wireshark which is 0
if all is well, !0 otherwise.

Thanx,
Jaap
