Right. In headers though, the traditional "static inline" idiom
indicates to the compiler that this function is a small
utility function that may not be used in all translation units
that the header is included in.  I.e. without the inline,
in some translation units you'd get:

  error: 'write_error' defined but not used [-Werror=unused-function]

cheers,
Pádraig.
