In a lot of C programs in the header files I see this:

#ifdef __cplusplus
extern "C" {
#endif

...

#ifdef __cplusplus
}
#endif

What exactly is this doing?

Thanks,

In C++ the type control is severe. Also C++ mangle function names. Code declared with extern "C" can't be averloaded. Also a lot of problems what appear if you use C functions in C++ disappear. For example function realloc. John Fill
