The concepts of register ESP and EBP are always confused. View and define esp as the stack top pointer, and EBP as the access Stack pointer. Still cannot be fully understood. Later I used a piece of assembly code to have a clear understanding of the two.The following is the assembly code for calling the test (INT P1, int P2) function according to the call Convention _ stdcall.Suppose that the pre-function S

### When the ESP law cannot be used-the use of EBP

1. Understand the EBP register There are many registers in the register, although their functions and use are no different, but in the long-term programming and use, in programmer habits, each register has been given a special meaning by default. For example, EAX is generally used for return values, and ECX is used for counting. In the win32 environment, the EBP register is used with the ESP value stored after the call is entered, so that the
