Hi guys.
Thanks to all anyway for answering.
I've found two nice solutions to solve my problem.
To be honest I've to mention that what my function receives a paramater
which is a PID and the function has to check if that process is still
running returning a value. Sorry for any misunderstanding. I agree that
my question was ambigous from that point of view.
This is also a fairly common requirement when a program leaves lock
files in a directory or a unix-domain socket etc. in /tmp or ~
# ls -l /var/run/*ttyS*
-rw-r--r-- 1 root root 4 Sep 6 13:46 /var/run/mgetty.pid.ttyS11
-rw-r--r-- 1 root root 6 Sep 8 18:46 /var/run/mgetty.pid.ttyS6
2. use kill with signal 0
uses BaseUnix;
if FpKill(wPID, 0) = 0 then
MessageDlg('OK', 'FpPid process is running', mtInformation, [mbOK], 0)
else
MessageDlg('OK', 'FpPid process is NOT running', mtError, [mbOK], 0);
I guess that solution 2 is the best as it asks immediately the kernel.
I agree.
