How to call C++ function from C?
- by claws
I know this.
Calling C function from C++:
If my application was in C++ and I had to call functions from a library written in C. Then I would have used
//main.cpp
extern "C" void C_library_function(int x, int y);//prototype
C_library_function(2,4);// directly using it.
This wouldn't mangle the name C_library_function and linker would find the same name in its input *.lib files and problem is solved.
Calling C++ function from C???
But here I'm extending a large application which is written in C and I need to use a library which is written in C++. Name mangling of C++ is causing trouble here. Linker is complaining about the unresolved symbols. Well I cannot use C++ compiler over my C project because thats breaking lot of other stuff. What is the way out?
By the way I'm using MSVC
