inline function in c

Question

Can inline function be declared in .h and defined once in .c?

Answer 1

inline function definitions need to be visible wherever the function is invoked. You can define the function in a .c file if you only want to use it within that .c file, otherwise you need to define it in a .h file so that the definition can be #included wherever it is needed.

Yes. It can get messy though here is a good read: http://www.greenend.org.uk/rjk/2003/03/inline.html

You can make a function static inline and include it on a header file:

square.h:

#ifndef SQUARE_H
#define SQUARE_H

static inline int square(int num) {
    return num * num;
}

#endif // SQUARE_H
