Method Stdio.File()->set_nonblocking()

Method set_nonblocking: void set_nonblocking()
Description: Sets this file to nonblocking operation.
Note: Nonblocking operation is not supported on all Stdio.File objects. Notably it is not guaranteed to be supported on objects returned by pipe() unless PROP_NONBLOCK was specified in the call to pipe() .

Method set_nonblocking: void set_nonblocking(function(mixed:int) read_callback, function(mixed:int) write_callback, function(mixed:int) close_callback)
void set_nonblocking(function(mixed:int) read_callback, function(mixed:int) write_callback, function(mixed:int) close_callback, function(mixed:int) read_oob_callback, function(mixed:int) write_oob_callback)
void set_nonblocking()
Description: This function sets a stream to nonblocking mode and installs the specified callbacks. See the set_*_callback functions for details about them. If no arguments are given, the callbacks will be cleared.
Note: As opposed to calling the set callback functions separately, this function will set all the callbacks and nonblocking mode atomically so that no callback gets called in between. That avoids races in case the backend is executed by another thread.
Note: Out-of-band data was not be supported on Pike 0.5 and earlier, and not on Pike 0.6 through 7.4 if they were compiled with the option '--without-oob'.
