Technically, you can, by using "extern inline".  But I agree that
putting the inline function in a header file is normally what you want.

The "inline" keyword is C++ does not, as many people assume, direct the
compiler to inline the function.  What it actually does is change the
linkage of the function.  C++ has three kinds of linkage for functions:
extern, static, and inline.
