Question

i have the following code:

QueryPerformanceCounter(&timeStart);
winMain::render(); //do stuff
QueryPerformanceCounter(&timeEnd);
numCounts = ( timeEnd.QuadPart - timeStart.QuadPart);

All the 3 variables are declared as LARGE_INTEGER, the code should work since im following a book example, but i get:

error C2679: ‘=’ binary no operator found which takes a right-hand operand of type LONGLONG
it might be ‘_LARGE_INTEGER &_LARGE_INTEGER::operator =(const _LARGE_INTEGER &)’

Answer 1

You are trying to assign a LONGLONG to a LARGE_INTEGER. No such assignment exists. Perhaps you meant to assign to numCounts.QuadPart.
