Bug ID: 37667
Summary: GetRawInputDeviceList() does not set an error code on
failure
Product: Wine
Version: 1.7.32
Hardware: x86
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: user32
Assignee: wine-bugs at winehq.org
Reporter: achurch+wine at achurch.org

gridl-fix.diff
When GetRawInputDeviceList() is passed a buffer which is too small, the
function should set the last error code to ERROR_INSUFFICIENT_BUFFER and return
failure (see
<http://msdn.microsoft.com/en-us/library/windows/desktop/ms645598(v=vs.85).aspx>).
However, the current Wine implementation does not set the last error code,
meaning that callers expecting to see ERROR_INSUFFICIENT_BUFFER will behave
incorrectly.
Patch attached (the patch is against wine-1.7.29 but the code is unchanged in
git).
