#3619 closed Bug (Fixed)

Return value of _WinAPI_LocalFree() is not consistent with what the documentation says

Reported by: tukangusil7@… Owned by: Jpm
Milestone: Component: Standard UDFs
Version: Severity: None
Keywords: LocalFree _WinAPI_LocalFree Cc:


Return Value according to the documentation
Success: True
Failure: False, call _WinAPI_GetLastError() to ...

In WinAPIMem.au3

Func _WinAPI_LocalFree($hMemory)
  Local $aResult = DllCall("kernel32.dll", "handle", "LocalFree", "handle", $hMemory)
  If @error Then Return SetError(@error, @extended, False)

  Return $aResult[0]
EndFunc   ;==>_WinAPI_LocalFree

If the error is caused by the DllCall(), the documentation is correct.

However, the return value of LocalFree() itself according to MSDN is:

  • If the function succeeds, the return value is NULL.
  • If the function fails, the return value is equal to a handle to the local memory object. To get extended error information, call GetLastError().

Thus, if LocalFree() returns 0 (which means successful), _WinAPI_LocalFree() returns False (which means failed).
