Debug Command 12 - Resume Thread Command
Parameters
Pid
If Tid is zero, all debuggee threads will be thawed.
Returns
The DBG_C_Resume command complements the DBG_C_Freeze command. A thread that has been resumed will function as if it were never frozen.
No error is returned if the thread was not previously frozen.
If the Tid is specified as zero, it will be set to the thread ID of the debuggee thread most recently scheduled to execute.
