10.17 Scheme->C interface

Most of the C functions interfacing with Guile/Scheme used in LilyPond are described in the API Reference of the Guile Reference Manual.

The remaining functions are defined in lily/lily-guile.cc, lily/include/lily-guile.hh and lily/include/lily-guile-macros.hh. Although their names are meaningful there’s a few things you should know about them.
