Subject: Running status of a process
Date: Wed, 21 Mar 2007 13:43:21 +0530 [thread overview]
Message-ID: <4600E921.5010106@sun.com> (raw)
Hi,
Can anyone point as to how can I obtain the information whether a
non-child process is still running?
I tried waitpid(pid, &status, WNOHANG) but always receive return value
as -1 with errno as ECHILD.
Since the processes I am waiting for is not the child of this process
from where I am calling waitpid() (ie, they are independant processes),
it might be a valid error but what is the other alternative?
Regards
Prasanta
