[Solved] Stopping a TProcess

[gilsonalencar]

Hi Folks,

Any idea how to stop a tcpdump application initiated by a TProcess.Executable? TProcess.Terminate(0) doesn't work.

The safe way: Kill using its PID
Easy way: Call .Free

According to Tcpdump's website:

Tcpdump will, ... , continue capturing packets until it is interrupted by a SIGINT signal (generated, for example, by typing your interrupt character, typically control-C)

For Windows use GenerateConsoleCtrlEvent(CTRL_C_EVENT, ..

Different OS, take a look at the source code of the debugger's InterruptTarget proc

Code: Text  [Select][+][-]

1.   TGDBMIDebugger = class(TCmdLineDebugger)
2.     procedure InterruptTarget; virtual;
3.

I have already read somethings about uses of PID. But, i didn't understand yet how to do it. The tcpdump stop to run under control+c command. I have been working with Linux and a simple call to TProcess.Free appears doesn't work too.

I would suggest using:

Code: Pascal  [Select][+][-]

1. uses
2.  ..., BaseUnix;
3. ...
4. FpKill(TargetPID, SIGINT);
5.  

I learned about it from the debugger's InterruptTarget proc

Code: Text  [Select][+][-]

1. {$IFDEF UNIX}
2.   FpKill(TargetPID, SIGINT);
3. {$ENDIF}        
4.

Thanks engkin.

The running process stopped with:

FpKill (TProcess.processID, SIGINT);
