__fastcall Calling Convention
The __fastcall calling convention specifies that arguments to functions are to be passed in registers, when possible.
The first two DWORD or smaller arguments are passed in ECX and EDX registers; all other arguments are passed right to left. (All arguments are passed RIGHT to LEFT in all calling convention except one i.e. __clrcall).
