twisted.internet._signals.installHandler(fd)

View Source
Install a signal handler which will write a byte to fd
when SIGCHLD is received.
This is implemented by installing a SIGCHLD handler that does nothing, setting the SIGCHLD handler as not allowed to interrupt system calls, and using signal.set_wakeup_fd
to do the actual writing.
Parameters | fd | The file descriptor to which to write when SIGCHLD is received. (type: int ) |
Function | noopSignalHandler | Undocumented |
