"class" used as a variable in C file

[Sudhanshu]

I have a c code that uses "class" as the variable name in a function
prototype

I want to use this in c++ file

How can I use it ? Any ideas

It is not guaranteed but:

extern "C"
{
#define class varclass
#include "header_with_class.h"
#undef class
}

Perhaps extern "C" is enough if the compiler doesn't interpret 'class'
in C part ?

The best solution would be to modify the header.

No, it's not. That only controls linkage, not compilation.

The best solution would be to modify the header.

Or to compile the C code to an obj file and link together, possibly
with a C++ wrapper function.

A pity.

The problem should not be the c code but the header associated to it.

In all cases, the C code must be compile as a C program into object file.
