When the int 0X80 instruction is executed, the system call number is stored in the register eax, and the parameters passed to the system call must be placed in the Register Ebx,ecx,edx,esi,edi in order, and when the system call is complete, the return value can be obtained in the register EAX. The function call that corresponds to
