Enumerating threads in a process

[Mistrel]

Source: http://blogs.msdn.com/oldnewthing/archi ... 37856.aspx

To identify the threads that belong to a specific process, compare its process identifier to the th32OwnerProcessID member of the THREADENTRY32 structure when enumerating the threads.

Code: Select all

Define te.THREADENTRY32

h=CreateToolhelp32Snapshot_(#TH32CS_SNAPTHREAD,0);

If (h<>#INVALID_HANDLE_VALUE)
	te\dwSize=SizeOf(te)
	If (Thread32First_(h,@te))
			Repeat
			If (te\dwSize>=OffsetOf(THREADENTRY32\th32OwnerProcessID)+SizeOf(te\th32OwnerProcessID))
				Debug "Process "+RSet(Hex(te\th32OwnerProcessID),4,"0")+" Thread "+RSet(Hex(te\th32ThreadID),4,"0")
			EndIf
			te\dwSize=SizeOf(te);
		Until Not (Thread32Next_(h,@te));
	EndIf
	CloseHandle_(h);
EndIf

I love PureBasic.

Can someone confirm if 'Process 0' and 'Thread 0' is not an error?

Hi Mistrel,

the PID 0 is the System Idle Process,

so is Right!
