Member Function Documentation

prepare()

bool prepare ( const LoopState & state, int64 * timeout_usecs_p )

protectedvirtual

Prepare the source for dispatching (true return) or polling (false).

Implements EventSource.

check()

bool check ( const LoopState & state )

protectedvirtual

Check the source and its PollFD descriptors for dispatching (true return).

Implements EventSource.

dispatch()

bool dispatch ( const LoopState & state )

protectedvirtual

Dispatch source, returns if it should be kept alive.

Implements EventSource.

destroy()

void destroy ( )

protectedvirtual

Reimplemented from EventSource.

raise()

void raise ( int8 signum )

static
