本文介绍了Visual C ++等同于__FILE__,__LINE__和__PRETTY_FUNCTION__的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
GCC编译器提供以下宏:
GCC compiler gives me the following macros:
- __FILE__ so that I can print out the file name + directory.
- __LINE__ so that I can print out the line number of where I'm printing from.
- __PRETTY_FUNCTION__ so that I can print out the pretty function name
相当于这些宏?
推荐答案
struct A
{
bool Test(int iDummyArg)
{
const char *szFile = __FILE__;
int iLine = __LINE__;
const char *szFunc = __FUNCTION__; // Func name
const char *szFunD = __FUNCDNAME__; // Decorated
const char *szFunS = __FUNCSIG__; // Signature
printf("%s\n", szFile);
printf("%d\n", iLine);
printf("%s\n", szFunc);
printf("%s\n", szFunD);
printf("%s\n", szFunS);
return true;
}
};
int wmain(int argc, TCHAR *lpszArgv[])
{
A a;
a.Test(10);
}
将打印:
c:\source\test_projects\blah\blah.cpp
14
A::Test
?Test@A@@QAE_NH@Z
bool __thiscall A::Test(int)
是错误,因为在我的文件的顶部真的有一些额外的东西。)
(The line number is "wrong" since there was really some extra stuff at the top of my file.)
