[GSoC][PATCH 2/2] qemu_domainjob: moved domain job APIs to a separate file

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



All the domain job related APIs were present in `qemu_domain.c`
along with the other domain APIs. In this patch, we move all the
qemu domain job APIs into a separate file.

Also, in this process, `qemuDomainTrackJob()`,
`qemuDomainFreeJob()`, `qemuDomainInitJob()` and
`qemuDomainObjSaveStatus()` were converted to a non-static
funciton and exposed using `qemu_domain.h`.
