The current qemudRegisterClientEvent() code is used both for registering the initial socket watch, and updating the already registered watch. This causes unneccessary complexity in alot of code which only cares about updating existing watches. The updating of a watch cannot ever fail, nor is a reference to the 'qemud_server' object required. This introduces a new qemudUpdateClientEvent() method for that case, allowing the elimination of unneccessary error checking and removal of the server back-reference in struct qemud_client. * qemud/qemud.h: Remove 'server' field from struct qemud_client. Add qemudUpdateClientEvent() method. Remove 'update' param from qemudRegisterClientEvent method * qemud/dispatch.c, qemud/qemud.c, qemud/remote.c: Update alot of code to use qemudUpdateClientEvent() instead of qemudRegisterClientEvent(). Move more logic from remoteRelayDomainEvent into remoteDispatchDomainEventSend.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
