[No it's not] Is it a bug ? (ThreadID() in windows)

[infratec]

Hi,

in an other thread something strange occured:

Code: Select all

Procedure test(dummy.i)
  Debug "CurrentProcessId: " + GetCurrentProcessId_()
  Debug "CurrentThreadId : " + GetCurrentThreadId_()
  ;Debug "CurrentThread   : " + GetCurrentThread_()
 
  Delay(20000)
 
EndProcedure


Define Thread.i = CreateThread(@test(), 0)

Debug "Outside Thread: " + ThreadParameter\Thread
Debug "Outside ThreadID: " + ThreadID(ThreadParameter\Thread)

Delay(25000)

Results in:



There is nothing to see of 364

Is it a bug, or what exactly returns ThreadID()

PB 5.72 x86 Win10 x64

The OS knows what it is. If we pass the result of PB's ThreadID() function to the OS to do something with, it happens:

Code: Select all

Procedure ThisIsAThread(void)
  Repeat
    Debug "I'm a thread!"
    Delay(1000)
  ForEver
EndProcedure

tid = CreateThread(@ThisIsAThread(), 0)
Delay(2000)
tid2 = ThreadID(tid) 
If TerminateThread_(tid2, 13)
  Debug "No you're not..."
EndIf
Delay(5000)
GetExitCodeThread_(tid2, @exitcode.i)
Debug exitcode

It is a handle to the thread, just like ImageID() returns an image handle. The documentation mentions this.

I am just a moment too late. Please see my example in this thread.

@Freak : Thank you

Here is the right interpretation:

Code: Select all

Import ""
  GetThreadId.l(Handle.i)
EndImport



Procedure test(dummy.i)
  Debug "CurrentProcessId      : " + GetCurrentProcessId_()
  Debug "CurrentThreadId       : " + GetCurrentThreadId_()
  Debug "Virtual CurrentThread : " + GetCurrentThread_()
  
  Debug "CurrentThreadId by OS via virtual CurrentThread : " + GetThreadID(GetCurrentThread_())
  
  Delay(20000)
 
EndProcedure


Define Thread.i = CreateThread(@test(), 0)

Debug "Outside Thread: " + Thread
Debug "Outside ThreadID PB (not the ThreadID, only a HANDLE) : " + ThreadID(Thread)
Debug "Outside ThreadID OS: " + GetThreadID(ThreadID(Thread))

Delay(25000)
