decipherWaitStatus :: CInt -> IO ProcessStatus Source #

data ProcessStatus Source #

The exit status of a process

Constructors

Exited ExitCode | the process exited by calling `exit()` or returning from `main`
Terminated Signal Bool | the process was terminated by a signal, the `Bool` is `True` if a core dump was produced Since: 2.7.0.0
Stopped Signal | the process was stopped by a signal
