Argument Passing and Naming Conventions

| Overview | How Do I

All arguments are widened to 32 bits when they are passed. Return values are also widened to 32 bits and

returned in the EAX register, except for 8-byte structures, which are returned in the EDX:EAX register

pair. Larger structures are returned in the EAX register as pointers to hidden return structures. Parameters

are pushed onto the stack from right to left.
