This works and is not awkward:

#include <stdio.h>

int my_func(int a, int b);

inline int my_func(int a, int b) {
   return a+b;
}

int main(void) {
   int a = 1;
   int b = 2;
   printf("Result of a+b: %i\n", my_func(a,b));
}

(You could just omit the separate declaration in this case, but it's
useful, or even required, in more complicated code.)

I changed your "int main()" to "int main(void)" because the latter is
more correct (that's a very minor point).

"__inline__" is a non-standard gcc extension.  Just use "inline" unless
you need to cater to pre-C99 compilers.

Your "my_func_SIGNATURE" just makes your code more difficult to read.
Every time I see it, I have to track down its definition to understand
what it means.
