与升压:: function_types函数调用约定 [英] function calling convention with boost::function_types

问题描述

我刚刚最近尝试用了boost :: function_types库，并且我已经遇到一个有点暴牙的。我想找出给定函数的调用约定，但我不太知道如何做到这一点。这是我到目前为止有：

这会产生如何，如果语句不能发现里面每个* _cc标记值错误。我怀疑它可能是与我定义宏的方式;该文档不是有关如何使用您的编译器设置额外的调用约定...在这里任何帮助将是AP preciated很清楚。

谢谢，

编辑：得到它的工作，好像我需要包括配置/ config.hpp，如下：

 的#define BOOST_FT_COMMON_X86_CCs 1
＃包括LT＆;提升/ function_types /配置/ config.hpp＆GT;
＃包括LT＆;升压/ type_traits.hpp＆GT;
＃包括LT＆;升压/ function_types / property_tags.hpp＆GT;
＃包括LT＆;升压/ function_types / is_function.hpp＆GT;
＃包括LT＆;升压/ function_types / is_function_pointer.hpp＆GT;
＃包括LT＆;升压/ function_types / parameter_types.hpp＆GT;
＃包括LT＆;升压/ function_types / result_type.hpp＆GT;
＃包括LT＆;升压/ function_types / function_arity.hpp＆GT;模板＆LT;类F＆GT;

    如果（的boost :: function_types :: is_function＆LT; F，stdcall_cc＆GT; ::值==真）{
        out.cc = cc_stdcall;
    }否则如果（的boost :: function_types :: is_function＆LT; F，fastcall_cc＆GT; ::值==真）{
        out.cc = cc_fastcall;
    }否则如果（的boost :: function_types :: is_function＆LT; F，cdecl_cc＆GT; ::值==真）{
        out.cc = cc_cdecl;
    }
}
 

解决方案

好像我只是缺少头文件中的一个（配置/ config.hpp）

 的#define BOOST_FT_COMMON_X86_CCs 1
＃包括LT＆;提升/ function_types /配置/ config.hpp＆GT;
＃包括LT＆;升压/ type_traits.hpp＆GT;
＃包括LT＆;升压/ function_types / property_tags.hpp＆GT;
＃包括LT＆;升压/ function_types / is_function.hpp＆GT;
＃包括LT＆;升压/ function_types / is_function_pointer.hpp＆GT;
＃包括LT＆;升压/ function_types / parameter_types.hpp＆GT;
＃包括LT＆;升压/ function_types / result_type.hpp＆GT;
＃包括LT＆;升压/ function_types / function_arity.hpp＆GT;模板＆LT;类F＆GT;

I've just been experimenting with the boost::function_types library recently, and I've come across a bit of a snag. I want to find out the calling convention of a given function, however I'm not quite sure how to do this. Here's what I have so far:

This produces an error about how it cannot find the *_cc tag values inside each if statement. I suspect it may have something to do with the way I'm defining the macros; the documentation isn't very clear about how to setup extra calling conventions with your compiler... Any help here would be appreciated.

Thanks,

EDITED: got it working, seems like I needed to include config/config.hpp, as below:

#define BOOST_FT_COMMON_X86_CCs 1
#include <boost/function_types/config/config.hpp>
#include <boost/type_traits.hpp>
#include <boost/function_types/property_tags.hpp>
#include <boost/function_types/is_function.hpp>
#include <boost/function_types/is_function_pointer.hpp>
#include <boost/function_types/parameter_types.hpp>
#include <boost/function_types/result_type.hpp>
#include <boost/function_types/function_arity.hpp>

template<class F>
inline void parse_cc(F f, func_info_s& out) {
    out.cc = cc_err;
    if (boost::function_types::is_function<F, stdcall_cc>::value == true) {
        out.cc = cc_stdcall;
    } else if (boost::function_types::is_function<F, fastcall_cc>::value == true) {
        out.cc = cc_fastcall;
    } else if (boost::function_types::is_function<F, cdecl_cc>::value == true) {
        out.cc = cc_cdecl;
    }
}

解决方案

It seems like I was simply missing one of the header files (config/config.hpp)

#define BOOST_FT_COMMON_X86_CCs 1
#include <boost/function_types/config/config.hpp>
#include <boost/type_traits.hpp>
#include <boost/function_types/property_tags.hpp>
#include <boost/function_types/is_function.hpp>
#include <boost/function_types/is_function_pointer.hpp>
#include <boost/function_types/parameter_types.hpp>
#include <boost/function_types/result_type.hpp>
#include <boost/function_types/function_arity.hpp>

template<class F>
inline void parse_cc(F f, func_info_s& out) {
    out.cc = cc_err;
    if (boost::function_types::is_function<F, stdcall_cc>::value == true) {
        out.cc = cc_stdcall;
    } else if (boost::function_types::is_function<F, fastcall_cc>::value == true) {
        out.cc = cc_fastcall;
    } else if (boost::function_types::is_function<F, cdecl_cc>::value == true) {
        out.cc = cc_cdecl;
    }
}
