Question

How are the parameters passed in a thiscall convention?

a.

All parameters are passed through the stack

b.

The first two parameters are passed through registers, the rest through the stack

c.

Parameters are passed in the reverse order compared to the cdecl convention

d.

Parameters are passed in the reverse order compared to the stdcall convention
