NAME
Sys::Virt::Event - An event loop contractDESCRIPTION
The "Sys::Virt::Event" module represents the contract for integrating libvirt with an event loop. This package is abstract and intended to be subclassed to provide an actual implementation.METHODS
- register($impl)
- Register an event loop implementation. The implementation should be a instance of a sub-class of the "Sys::Virt::Event" package.
- $self->_run_handle_callback($watch, $fd, $events, $cb, $opaque)
- A helper method for executing a callback in response to one of more $events on the file handle $fd. The $watch number is the unique idenifier associated with the file descriptor. The $cb and $opaque parameters are the callback and data registered for the handle.
- $self->_run_timeout_callback($timer, $cb, $opaque)
- A helper method for executing a callback in response to the expiry of a timeout identified by $timer. The $cb and $opaque parameters are the callback and data registered for the timeout.
- $self->_free_callback_opaque($ff, $opaque)
- A helper method for freeing the data associated with a callback. The $ff and $opaque parameters are the callback and data registered for the handle/timeout.
CONSTANTS
FILE HANDLE EVENTS
When integrating with an event loop the following constants define the file descriptor events- Sys::Virt::Event::HANDLE_READABLE
- The file descriptor has data available for read without blocking
- Sys::Virt::Event::HANDLE_WRITABLE
- The file descriptor has ability to write data without blocking
- Sys::Virt::Event::HANDLE_ERROR
- An error occurred on the file descriptor
- Sys::Virt::Event::HANDLE_HANGUP
- The remote end of the file descriptor closed
