Detailed Description

This class is an abstraction of platform dependent polling API.

It abstracts platform specific APIs like epoll, /dev/poll, kqueue, poll and select.

It provides platform independent functionality for polling file descriptions in an efficient way

Constructor & Destructor Documentation

booster::aio::reactor::reactor ( int hint = use_default )

Create a new polling device using hint recommendation. If provided device is not supported the default is used

std::string booster::aio::reactor::name ( ) const

Get the actual name of the polling device used.

Poll for the events, wait at most timeout microseconds. Save up to n values to the events vector.

Returns number of events recorded. Returns 0 if timeout occurred.

If error occurs throws system::system_error

Poll for the events, wait at most timeout microseconds. Save up to n values to the events vector.

Returns number of events recorded. Returns 0 if timeout occurred.

If error occurs, the error code is assigned to e

void booster::aio::reactor::remove ( native_type fd )

inline

Removes the fd from the watch list

If error occurs throws system::system_error

void booster::aio::reactor::remove	(	native_type	fd,
		system::error_code &	e
	)

inline

Removes the fd from the watch list

If error occurs, the error code is assigned to e

void booster::aio::reactor::select	(	native_type	fd,
		int	flags
	)

Add fd to watch list, flags can be a or mask of io_events::in, io_events::out and io_events::err

If flags=0 removes the fd from the watch list

If error occurs throws system::system_error

void booster::aio::reactor::select	(	native_type	fd,
		int	flags,
		system::error_code &	e
	)

Add fd to watch list, flags can be a or mask of io_events::in, io_events::out and io_events::err

If flags=0 removes the fd from the watch list

If error occurs, the error code is assigned to e
