OS2::Process - exports constants for system() call on OS2.
use OS2::Process; $pid = system(P_PM+P_BACKGROUND, "epm.exe");
the builtin function system() under OS/2 allows an optional first argument which denotes the mode of the process. Note that this argument is recognized only if it is strictly numerical.
You can use either one of the process modes:
P_WAIT (0) = wait until child terminates (default) P_NOWAIT = do not wait until child terminates P_SESSION = new session P_DETACH = detached P_PM = PM program
and optionally add PM and session option bits:
P_DEFAULT (0) = default P_MINIMIZE = minimized P_MAXIMIZE = maximized P_FULLSCREEN = fullscreen (session only) P_WINDOWED = windowed (session only) P_FOREGROUND = foreground (if running in foreground) P_BACKGROUND = background P_NOCLOSE = don't close window on exit (session only) P_QUOTE = quote all arguments P_TILDE = MKS argument passing convention P_UNRELATED = do not kill child when father terminates
