Application Adding Argument

    I created a simple application and if i go into the package contents and run the executable it runs fine, but if i click on the icon and try to run it the application is adding an argument to the executable and i get this

    paraprof: unknown option '-psn_0_2621441'
    Usage: paraprof [--pack <file>] [--dump] [-p] [-m] [-i] [-f <filetype>] <files/directory>

    where paraprof is the name of the executable.

    does anyone know why it is adding the -psn_0_2621441 when i try to run it from the icon?

    PSN is the process serial number, which OS X passes as an argument to all applications. It's used for various system things for identifying and discriminating different processes (it will be unique for each time any process is launched). From the Apple dev docs:

    *All applications = all applications which connect to Carbon or Cocoa, from what I can tell. There are a number of unix processes that don't get PSNs.

    Edit: ..or maybe its processes which connect to the window server?

    How do I get the path of a file that is dropped onto my icon? All I get is the same -pxn-XXXX stuff, no filename.
