DllCall to GetExitCodeProcess
Keywords: GetExitCodeProcess DllCall tListProc Process Handle Exit Code Exitcode IntControl 64 Run RunWait RunShell OpenProcess MsgWaitForMultipleObjects WaitForSingleObject
GetExitCodeProcess Function
Retrieves the termination status of the specified process.Sample 1:
;; Create a test process
Pid = RunShell( "notepad.exe", "", "", @NORMAL, @GETPROCID)
; Boilerplate
nExitCode = 2147483647 ; Whatever
hKernel32 = DllLoad("kernel32")

hhWaitProcess = BinaryAlloc(4)

; Need both query(1024) and sync(1048576) access
hWaitProcess = DllCall(hKernel32,long:"OpenProcess",long:1024|1048576,long:0,long:Pid)

; Suspend until process exits
nResult = 0

If nResult == -1 Then Break
; Check for process signaled (0 return means process signaled)
If DllCall(hKernel32 ,long:"WaitForSingleObject", long:hWaitProcess, long:0) == 0 Then Break
Yield() ; Give up the rest of a CPU slice to be on the safe side
EndWhile
; Check for sync errors
If nResult == -1 Then Message( "Error", "System error = ":DllLastError())
Then Goto cleanup
; Get the process exit code
DllCall(hKernel32,long:"GetExitCodeProcess",long:hWaitProcess,lpbinary:hExitCode)
