Detailed Description

Type of the device status register.

Definition at line 32 of file virtio.

Member Function Documentation

running()

bool L4virtio::Svr::Dev_status::running ( ) const

inline

Check if the device is in running state.

Returns

true if the device is in running state.

The device is in running state when acked(), driver(), features_ok(), and driver_ok() return true, and device_needs_reset() and failed() return false.
