Function	setNonBlocking	Make a file descriptor non-blocking.
Function	setBlocking	Make a file descriptor blocking.
Function	readFromFD	Read from file descriptor, calling callback with resulting data.
Function	writeToFD	Write data to file descriptor.
Function	_setCloseOnExec	Make a file descriptor close-on-exec.
Function	_unsetCloseOnExec	Make a file descriptor close-on-exec.

def setNonBlocking(fd): (source)

Make a file descriptor non-blocking.

def setBlocking(fd): (source)

Make a file descriptor blocking.

def _setCloseOnExec(fd): (source)

Make a file descriptor close-on-exec.

def _unsetCloseOnExec(fd): (source)

Make a file descriptor close-on-exec.

def readFromFD(fd, callback): (source)

Read from file descriptor, calling callback with resulting data.

If successful, call 'callback' with a single argument: the resulting data.

Returns same thing FileDescriptor.doRead would: CONNECTION_LOST, CONNECTION_DONE, or None.

Parameters	fd	non-blocking file descriptor to be read from. (type: `int`)
	callback	a callable which accepts a single argument. If data is read from the file descriptor it will be called with this data. Handling exceptions from calling the callback is up to the caller. Note that if the descriptor is still connected but no data is read, None will be returned but callback will not be called.
Returns	CONNECTION_LOST on error, CONNECTION_DONE when fd is closed, otherwise None.

def writeToFD(fd, data): (source)

Write data to file descriptor.

Returns same thing FileDescriptor.writeSomeData would.

Parameters	fd	non-blocking file descriptor to be written to. (type: `int`)
	data	bytes to write to fd. (type: `str` or `buffer`)
Returns	number of bytes written, or CONNECTION_LOST.
