Q29.
Why is the function not a _fastcall calling convention?

a.

because it receives parameters through ECX and EDX

b.

because it uses a standard EBP stack frame

c.

because it doesn't take any registers from the caller

d.

because it initializes every register that is accessed within the function itself

Discuss
Answer: (c).because it doesn't take any registers from the caller Explanation:Every register that is accessed within the function itself is initialized, indicating that it's not a _fastcall calling convention, which receives parameters through ECX and EDX.
