Member Function Documentation

expired()

virtual void L4::Ipc_svr::Timeout::expired ( )

pure virtual

callback function to be called when timeout happened

Note

The timeout object is already dequeued when this function is called, this means the timeout may be safely queued again within the expired() function.

Implemented in Block_device::Errand::Errand, and Block_device::Errand::Poll_errand.

Referenced by L4::Ipc_svr::Timeout_queue::handle_expired_timeouts().

Here is the caller graph for this function:

timeout()

l4_kernel_clock_t L4::Ipc_svr::Timeout::timeout ( ) const

inline

return absolute timeout of this callback.

Returns

absolute timeout for this instance of the timeout.
