Line 173: − − Many messages which require the PID also require a placeholder u64 value passed in the input parameters. In these cases the OverwriteClientProcessId method is called to replace the value before it is used.

Sysmodules load the last u64 of rawdata when handling the PID. This is not written by kernel. For sysmodule handling:
* In some cases: The rawdata_u64 is written to stack as the initial PID, but this is never used since the get-pid function always overwrites the output PID when it returns retval 0.
* In some cases: these commands require a placeholder u64 value passed in the input parameters, as mentioned above. In these cases the OverwriteClientProcessId method is called to replace the value before it is used.
* In other cases: The rawdata_u64 is compared with the PID from the descriptor. On mismatch and when rawdata_u64!=0, error 0x60A is returned. The PID value passed to the cmdhandler vtable funcptr is the rawdata_u64.
