.. c:function:: int PySignal_SetWakeupFd(int fd)
This utility function specifies a file descriptor to which a ``'\0'`` byte will
be written whenever a signal is received. It returns the previous such file
descriptor. The value ``-1`` disables the feature; this is the initial state.
This utility function specifies a file descriptor to which the signal number
is written as a single byte whenever a signal is received. *fd* must be
non-blocking. It returns the previous such file descriptor.
The value ``-1`` disables the feature; this is the initial state.
This is equivalent to :func:`signal.set_wakeup_fd` in Python, but without any
error checking. *fd* should be a valid file descriptor. The function should
only be called from the main thread.
.. versionchanged:: 3.5
On Windows, the function now also supports socket handles.
