WHY IS HANDLE NECESSARY HERE?

Question

HANDLE aa = OpenProcess(PROCESS_ALL_ACESS, FALSE, id);

why is HANDLE necessary here?

Answer 1

DWORD is an unsigned 32 bit integer used specifically in windows...

It is used to represent constants or variables for switches...

In the function I posted earlier,

HANDLE out= GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(out,FOREGROUND_RED);

FOREGROUND_RED is a WORD, which is 16 bits.

Similarly, there is DWORD to represent larger data where WORD is insufficient...

It is normally used to create large pointers for storing useful data,
Eg - Console Stats, Procedures, Current Messages, etc...

You may use it anywhere where you have to store a large integer or memory...

But is it usually not so preffered as WORD proves to be sufficient most of the time...
