Checking whether the exe is running or not

[plmanikandan]

Hi,

I am having a exe application which will be triggered by a external
program.I need to check whether the exe is already running or not.If
the exe is runing i need to discard the external program request.Is
there any function available in c to check whether exe is running or
not


Regards,

ISO C's standard library possesses no such function, but your implementation
may provide one. I suggest you consult a newsgroup devoted to discussing
programming on your particular platform, whatever that may be.

There is not.

Absent some platform specific (hint, hint) method, you could have the
application create a `lock' file of some sort at startup and remove it
when the program ends; if the file exists, you'd know it was running
(or, at least, hadn't terminated normally).

Entirely platform dependent. You need access to some mutual exclusion
device. The nature and character of it is entirely dependent on your
platform.

comp.unix.programmer would be a good place to ask if you're using a Unix
or POSIX platform.

Is you are using UNIX.You can find it out like this

ps aux|grep <filename>

If you are using windows,pressing Ctrl+Alt+Del and see if the .exe file
is in the list.

Not necessarily. The app may have been executed via a link with a different
name than the actual program.

If you are using windows,pressing Ctrl+Alt+Del and see if the .exe file
is in the list.

This requires user intervention. The OP obviously wants to check
programmatically.
