So I want to know the memory usage of CreateDIBSection()

I already tried task manager to find the memory leak but not able to find it.

if i can get to know the memory which CreateDIBSection is consuming everytime it is getting called.

How much memory will the ppvBits takes in CreateDIBSection.

While pasting the code i removed that information.
