getProcessStatus ∷ Bool → Bool → ProcessID → IO (Maybe ProcessStatus)

getProcessStatus blk stopped pid calls waitpid, returning Just tc, the ProcessStatus for process pid if it is available, Nothing otherwise. If blk is False, then WNOHANG is set in the options for waitpid, otherwise not. If stopped is True, then WUNTRACED is set in the options for waitpid, otherwise not.

Note: Because getProcessStatus of System.Posix.Process module doesn't give information about ptrace events, this is a re-implementation that gives information about ptrace events.

getGroupProcessStatus ∷ Bool → Bool → ProcessGroupID → IO (Maybe (ProcessID, ProcessStatus))

getGroupProcessStatus blk stopped pgid calls waitpid, returning Just (pid, tc), the ProcessID and ProcessStatus for any process in group pgid if one is available, Nothing otherwise. If blk is False, then WNOHANG is set in the options for waitpid, otherwise not. If stopped is True, then WUNTRACED is set in the options for waitpid, otherwise not.

Note: Because getGroupProcessStatus of System.Posix.Process module doesn't give information about ptrace events, this is a re-implementation that gives information about ptrace events.

getAnyProcessStatus ∷ Bool → Bool → IO (Maybe (ProcessID, ProcessStatus))

getAnyProcessStatus blk stopped calls waitpid, returning Just (pid, tc), the ProcessID and ProcessStatus for any child process if one is available, Nothing otherwise. If blk is False, then WNOHANG is set in the options for waitpid, otherwise not. If stopped is True, then WUNTRACED is set in the options for waitpid, otherwise not.

Note: Because getAnyProcessStatus of System.Posix.Process module doesn't give information about ptrace events, this is a re-implementation that gives information about ptrace events.
