The function declaration scheme is as follows.
- For plugins and codecs, no file access functions are declared since
in this case they are accessed via the rb API.
- For application build (target or sim), they are declared as macros
which expand to app_xxx. I.e. the functions that get declared after
the preprocessing are app_open, app_remove etc. These functions are
implemented using the host functions open, remove etc.
- For non-app simulator builds, they are declared as macros
which expand to sim_xxx. I.e. the functions that get declared after
the preprocessing are sim_open, sim_remove etc. These functions are
implemented using the host functions open, remove etc.
