C++ (Cpp) hMap Examples

Example #1

File: DBWinReader.cpp Project: janwilmans/DebugViewPP

Handle CreateDBWinBufferMapping(bool global)
{
	Handle hMap(CreateFileMapping(nullptr, nullptr, PAGE_READWRITE, 0, sizeof(DbWinBuffer), GetDBWinName(global, L"DBWIN_BUFFER").c_str()));
	if (GetLastError() == ERROR_ALREADY_EXISTS)
		throw std::runtime_error("CreateDBWinBufferMapping");
	return hMap;
}

Example #2

File: DBWinBuffer.cpp Project: JayceM6/DebugViewPP

bool HasGlobalDBWinReaderRights()
{
	//if (IsWindowsVistaOrGreater())
	{
		Win32::Handle hMap(::CreateFileMapping(nullptr, nullptr, PAGE_READWRITE, 0, sizeof(DbWinBuffer), L"Global\\DBWIN_BUFFER"));
		return hMap != nullptr;
	}
	return false;
}

Example #3

File: DBWinBuffer.cpp Project: JayceM6/DebugViewPP

bool IsDBWinViewerActive()
{
	Win32::Handle hMap(::OpenFileMapping(FILE_MAP_READ, false, L"DBWIN_BUFFER"));
	return hMap != nullptr;
}
