void DUNE::System::IOMultiplexing::del

(

void *

src

)

Remove os-specific i/o handle from the polling pool.

Only supports unix file descriptors so far.

Parameters

[in]

src

pointer to os-specific i/o handle.

bool DUNE::System::IOMultiplexing::poll

(

double

timeout

)

Wait for new input from the i/o handle pool.

Parameters

[in]

timeout

timeout in seconds, negative for no timeout.

Returns

true if there is i/o activity, false otherwise.
