关于__stdcall 和 __cdecl的问题

[liu_feng_fly]

各位大侠：
我有个问题。就是我知道c语言调用函数是__cdecl的。有调用者清空栈，而其他语言是__stdcall的，函数返回时自己要清空栈。但我还是不太理解。我知道用__cdecl有一个好处是可以实现可变参数，如printf()函数。但我们是否可以自己编出来这样的函数呢？因为除了函数库中的函数，我还没见过自己编出来的，向各位请教了！！谢谢！！

从 msdn里查 va_list va_arg 等

我在以前的贴子中回答过这个问题喔...

最主要的区别是:
__stdcall由被调用者清栈.WINDOWS API函数使用这种方式.
__cdecl由调用者清栈.C/C++使用这种方式

__stdcall:
Argument-passing, order Right to left.
Argument-passing convention, By value, unless a pointer or reference type is passed.
Stack-maintenance responsibility, Called function pops its own arguments from the stack.
Name-decoration convention, An underscore (_) is prefixed to the name. The name is followed by the at sign (@) followed by the number of bytes (in decimal) in the argument list. Therefore, the function declared as int func( int a, double b ) is decorated as follows: _func@12
Case-translation convention, None


__cdecl:
Argument-passing, order Right to left
Stack-maintenance, responsibility Calling function pops the arguments from the stack
Name-decoration convention, Underscore character (_) is prefixed to names
Case-translation, convention No case translation performed

不好意思,第一句断句错啦
Argument-passing, order Right to left.
应该是
Argument-passing order, Right to left.

就是说参数进栈顺序是由右而左喽.
这两种方式的进栈顺序是一样的.

我更想知道如何自己编一个可变参数的函数

照着printf写一个不就完了嘛
