Hi. All.
I rewrote the patched.
But I modified the feature for the situation @result pointer is NULL.
Though before it does not forcely wait, I think it is not meanless because
@result pointer is always NULL.
And @timeout must be following
VIR_DOMAIN_QEMU_AGENT_COMMAND_BLOCK(-2) : does not block and wait forever.
VIR_DOMAIN_QEMU_AGENT_COMMAND_DEFAULT(-1) : use default time for waiting
VIR_DOMAIN_QEMU_AGENT_COMMAND_NOWIAT(0) : does not wait and out soon
positive value : wait for pointed seconds.
In addition, I added the some options for virsh command qemu-agent-command
--block : it means taht @timeout is VIR_DOMAIN_QEMU_AGENT_COMMAND_BLOCK.
--async : it means taht @timeout is VIR_DOMAIN_QEMU_AGENT_COMMAND_NOWIAT.
--timeout @seconds : @seconds must be positive value and it means that @timeout
is positive value case.
These upper options are exclusive.
If no options are given, it means taht @timeout is IR_DOMAIN_QEMU_AGENT_COMMAND_DEFAULT.
virsh # help qemu-agent-command
