inline function defined in the header file generates linker error. It seems like linker does not recognize __INLINE or just inline, and gives error saying "multiple definition". static __INLINE does not generate an error. Any idea what's going on?

Thanks

1. Prevent multiple inclusion of the header:

#ifndef MAIN_H_
#define MAIN_H_
/* code */
#endif /* MAIN_H_ */

and "multiple definition" will go away.
2. static means "visible only in this file". If you declare static function or variable in header, then the function will be visible in all files where this header included but as a copy of the declaration.

Ignoring the variables, since we're talking inline functions copying is irrelevant and static inline is an acceptable solution.
