[Qemu-devel] [PATCH v12 for-4.1 02/11] qemu_thread: supplement error handling for qemu_X_start_vcpu |
Date: |
Mon, 25 Mar 2019 01:21:39 +0800 |
From: Fei Li <address@hidden>
The callers of qemu_init_vcpu() already passed the **errp to handle
errors. In view of this, add a new Error parameter to qemu_init_vcpu()
and all qemu_X_start_vcpu() functions called by qemu_init_vcpu() to
propagate the error and let the further callers check it.
Besides, make qemu_init_vcpu() return a Boolean value to let its
callers know whether it succeeds.
