OpenProcess function with two dwDesiredAccess

Based on microsoft documentation, dwDesiredAccess parameter can be one or more of the process access rights.

I want to pass two different dwDesiredAccess (PROCESS_QUERY_INFORMATION and PROCESS_TERMINATE) when I call openProcess function. Can anyone show me how to call the function?

HANDLE hprocess = OpenProcess(PROCESS_QUERY_INFORMATION, 0, static_cast<DWORD>(proc.th32ProcessID));

Please note that the above code is for one access right.

Like most Win32 functions where you can set multiple parameters in a single argument, you need to simply bitwise OR in the parameters together:

HANDLE hprocess = OpenProcess(PROCESS_QUERY_INFORMATION|PROCESS_TERMINATE, 0, static_cast<DWORD>(proc.th32ProcessID));
