<code>__FILE__</code> and <code>__LINE__</code> are standard, and I'm rather certain Microsoft compilers have essentially always had them.

<code>__PRETTY_FUNCTION__</code> is a gcc feature.

Yes Visual C++ has them or an equivalent. See the responses here:

Also note that despite the upper case used, they aren't macros. They're variables.

blocks|key|285851|text|我知道MSVC提供了__FILE__和__LINE__，这两个都是标准宏。他们还提供__FUNCTION__，我相信这就是你想要的。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|285852|entityMap^0|A|8|J|8|16|C|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|O|8|@]|D|@]|E|$]]]|G|$]]

I know that MSVC offers <code>__FILE__</code> and <code>__LINE__</code>, both of which are Standard macros. They also offer <code>__FUNCTION__</code>, which I believe is what you're looking for,

blocks|key|285864|text|__FILE__和__LINE__是自C89以来的标准。__PRETTY_FUNCTION__是一个GCCism。__func__是一个C99ism+(与GCCisms不同)，它很可能在Visual+C%2B%2B中可用；它与__PRETTY_FUNCTION__不完全相同，但可能足够接近您的目的。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|285865|entityMap^0|0|8|9|8|S|J|1L|8|31|J|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]|$9|Q|A|R|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|S|8|@]|D|@]|E|$]]]|G|$]]

<code>__FILE__</code> and <code>__LINE__</code> are standard since C89. <code>__PRETTY_FUNCTION__</code> is a GCCism. <code>__func__</code> is a C99ism which (unlike GCCisms) may well be available in Visual C++; it is not precisely the same as <code>__PRETTY_FUNCTION__</code> but it may be close enough for your purposes.

GCC compiler gives me the following macros:

<ul>
<li><code>__FILE__</code> so that I can print out the file name + directory.</li>
<li><code>__LINE__</code> so that I can print out the line number of where I'm printing from.</li>
<li><code>__PRETTY_FUNCTION__</code> so that I can print out the pretty function name</li>
</ul>

Does Visual C++ have the equivalent of these macros? A side question is, are these standard for C++ compilers?

Visual C++ equivalent of __FILE__ , __LINE__ and __PRETTY_FUNCTION__

GCC编译器给了我以下宏：__FILE__，这样我就可以打印出文件名+ directory.__LINE__，这样我就可以打印出打印from.__PRETTY_FUNCTION__所在位置的行号，这样我就可以打印出漂亮的函数名Visual C++是否有这些宏的等价物？一个附带的问题是，这些是C++编译器的标准吗？
