Hi,

I need to know if a binary is executing or not. I just have the path to the 
binary e.g. /Applications/MyApp.app/Contents/MacOS/MyApp

There's NSRunningApplication method runningApplicationsWithBundleIdentifier: , 
but I have other binaries which are embedded in this app which don't have a 
bundle id. And I want to know if they are running or not.

Cocoa doesn't seem have any such specific API for this purpose. NSFileHandle 
provides a valid handle (for writing) even if the binary is executing.

Is there any method like open() or something which would fail if binary is 
executing. Tried open() with flags O_EXLOCK but no luck yet.

Is this even possible?

Best,
Nick
