/*
|
|
* Including system's headers inside `extern "C" { ... }` is not safe, as system
|
|
* headers may have C++ code in them, and C++ code inside extern "C"
|
|
* leads to syntatically incorrect code.
|
|
*
|
|
* This is because putting code inside extern "C" won't make __cplusplus define
|
|
* go away, that is, the system header being included thinks is free to use C++
|
|
* as it sees fits.
|
|
*
|
|
* Including non-system headers inside extern "C" is not safe either, because
|
|
* non-system headers end up including system headers, hence fall in the above
|
|
* case too.
|
|
*
|
|
* Conclusion, includes inside extern "C" is simply not portable.
|
|
*
|
|
*
|
|
* This header helps surface these issues.
