问题描述
I have a piece of code which uses __COUNTER__ macro to generate unique names for variables.
Is this code portable ? I know that GCC and MSVS support it. What's about other compilers ? Is the macro defined by standard (as far as I know before C++14 it wasn't).
解决方案
It's definitely not standard.
It's a compiler extension (GNU C extensions)
and a Microsoft-specific one,
also supported by clang as language extension.
The standard doesn't mention it anywhere.
