    A non-modal call similar to system()

    Hi. system() is provided by stdlib.h as a mechanism to run a system command. This call waits for the invoked command to finish before passing the result back to the invoking program. Is there a call similar to system() that does not wait for the command to finish?

    If you are on a Windows box... #include <windows.h> and call ShellExecute()

    Don't know what it would be for Linux...

    I don't know if there's any better option, but in Linux, you could fork a child process, then call one of the exec functions. It's equivalent in terms of parent/child relationship and simultaneous execution. Not sure what other differences there may be in environment, real and effective IDs, etc.
