delete[] mechanics

[ProgrammerC++]

the number of elements is placed in a DWORD 4 bytes before the returned pointer...

so if you would do this..

DWORD * array = new DWORD[5];

then this is true:

array[-1] == 5

this way it is know to the compiler how many elements are in the array, used only for the constructors and even more the destructors...



note: this is not completely true.. see discussion below.
