How to get PID of a process from a C program

[Srini]

Hi

Could someone please let me know how to get a PID of a process from a
C Program on Windows platform.

e.g
I have a C program executable called myprog.exe and there could be
several instances of this program running. I would like to know the
PID(process id) of a given instance of myprog.exe.

I guess I can call the system() function and execute the following DOS
command.
tasklist /fi "IMAGENAME eq myprog.exe" /nh /fo "TABLE"

But this will give me a list of all the instances of myprog.exe

My questions is how can i figureout the PID of the instance I am
running from within myprog.c?

Thanks a lot for your time in advance.

Well, in "C" you probably can't. In your particular dialect of C, there
may be a way. Why not check the documentation for your particular flavor
of C? To get the PID, you may consider looking for a function that may
be called something like "getpid" perhaps.

By asking in a win32 programming newsgroup? This is not a C language
question.

Basically, you compute the sum of at least three terms:

Kp * e(n)
Ki * (e(n)+e(n-1)+e(n-2)...+e(1)+e(0))
Kd * (e(n)-e(n-1)

Customizations abound.

Oh, that kind of PID. No way to do that in standard C, whereas it is
quite possible to do the computations for a Proportional, Integral,
Derivative control loop in standard C.

The Windows newsgroups are that'a'way.
