EnterCriticalSection() always throws an error

[Qriist]

Confounding error here. I was looking around the forums for ways to improve the performance of my first MT script when I came across the suggestion to use a Critical Object for communication between threads. Creating the object works fine but trying to take control of it does not.

EnterCriticalSection() will always provide me with the following error:

(LeaveCriticalSection() incidentally throws the same error - I assume it's related.)

This is all that is required for me to get the error. Adding a long sleep after CriticalObject() or adding keys to obj does not make a difference. I have also tried temporarily disabling my antivirus just incase that operation was getting flagged somehow.

Code: Select all

obj := CriticalObject()	;works
EnterCriticalSection(obj)	;throws error
LeaveCriticalSection(obj)	;also throws its own error

This sample code from @HotKeyIt in another thread works fine and produces the expected incrementing tooltip. Note the lack of EnterCriticalSection().

Code: Select all

obj := CriticalObject() ; Create new critical object
Loop 4 ; Create 4 Threads.
 AhkThread%A_Index% := AhkThread("obj:=CriticalObject(" (&obj) ")`nLoop`nobj[" A_Index "]:= A_Index")
 
Loop ; Show current content of object.
 ToolTip % obj.1 "`n" obj.2 "`n" obj.3 "`n" obj.4
Esc::ExitApp

PC environment:

• Win10 Pro Build 19045 x64, running as admin
• freshly downloaded latest version of AHK_H v1 x64
• ESET Smart Security antivirus

What can I do to fix this error?

ure trying to pass a "Critical Object" as is, which is a plain ahk Object, to the winapi EnterCriticalSection, which instead expects to receive a pointer to a CRITICAL_SECTION. u cant pass garbage to to those types of function and expect them not to blow up ur program
