Suspends the specified virtual machine.
PRL_HANDLE PrlVm_Suspend( PRL_HANDLE hVm );
PrlApiVm.h
A handle of type PHT_JOB containing the results of this asynchronous operation or PRL_INVALID_HANDLE if there's not enough memory to instantiate the job object.
When a running virtual machine is suspended, the state of the virtual machine processes is saved into a file on the host and after that the machine is stopped. To resume the machine, use the PrlVm_Resume function. If, after suspending a machine, you don't want to resume it but would like to return to the previous state, you may call the PrlVm_DropSuspendedState function.
To get the return code from the PHT_JOB object, use the PrlJob_GetRetCode function. Possible values are:
PRL_ERR_INVALID_ARG - invalid handle or null pointer was passed.
PRL_ERR_SUCCESS - function completed successfully.
