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'.
