Bug ID: 51833
Summary: GetModuleFileNameW no longer works with large buffers
Product: Wine
Version: unspecified
Hardware: x86-64
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: kernel32
Assignee: wine-bugs at winehq.org
Reporter: wine at 2ar.nl
Regression SHA1: 43d14fd808bb965762bb6c76027bbe26ba936f82
Distribution: ---
The recent change 'Implement kernelbase.GetModuleFileNameW using
ntdll.LdrGetDllFullName' (bug 49344) broke passing large buffers (>=32768
characters) to GetModuleFileNameW, as done by cygwin.
Possible fix:
name.MaximumLength = (size < 0xffff / sizeof(WCHAR) ? size : 0xffff /
sizeof(WCHAR)) * sizeof(WCHAR);
Comment from Nikolay Sivov: we could probably min() it in ints, to avoid this
16bit overflow.
