Sleep() 内联汇编调用有效但生成运行时 check-failure

Question

正如我的问题标题所说，sleep() 函数正常工作（以及 C 函数中的所有其他函数调用，问题是在它完成后运行我收到一条错误消息：

"Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention."

我相信我在调用睡眠函数时处理寄存器的方式是正确的，因为它确实有效，我发布了整个函数以防万一需要它来检测我可能错放堆栈内容的位置另一个函数调用。

该函数主要是打印一部电梯从底部的最后一层到 top-most 层。

评论太多了。我的意思是压入和弹出您有兴趣保留的寄存器，包括您在 esi <-> ebx 和 edi <-> ecx.

中处理的那些寄存器

_sleep:
push    ecx                 // save the regs
push    edx
push    ebp

mov     eax, sleepTime      // func argument
push    eax                 // pushes the sleep time input
call    Sleep               // sleep() call
pop     eax                 // clean off stack

pop     ebp                 // restore regs
pop     edx
pop     ecx

WinApi Sleep() function follows the STDCALL calling convention。它在 returns 时已经清理了堆栈。当您执行相同操作时，堆栈为 "overcleaned" ;-)。删除行：

    pop eax                //cleans the stack

不知道你用的是什么编译器。我的编译器 (Visual Studio 2010) 需要再次调用 Sleep():

call dword ptr [Sleep]

Sleep() 内联汇编调用有效但生成运行时 check-failure

Sleep() inline assembly call works but generates runtime check-failure

c

assembly

stack

sleep
