Pascal==callback==winapi==__stdcall

VC Inside: Pascal==callback==winapi==__stdcall _stdcall is the default invocation of the PASCAL program, usually used in the Win32 API, the function uses a right-to-left stack, and then empties itself at the exit.     After the VC compiles the function, it adds an underscore prefix to the function name, followed by the function name with the "@" and the number of bytes of the parameter. _cdecl are the default calling methods for C and C + + programs. Each function that calls it contains the code that empties the stack, so the resulting executable file size is larger than the call to the _stdcall function. The function uses a right-to-left compression stack. When a VC compiles a function, it will precede the function name with an underscore prefix. Is the MFC default calling convention.
In terms of Pascal, you just have to figure it out: the function that declares the calling convention is the stack itself, and the __cdecl function is cleared by the caller. When actually used, the person thinks the biggest difference is: __cdecl function parameter number can be declared as indeterminate, such as printf,scanf, and Pascal's function can not do this, if so it does not know the number of arguments.
