Guile Reference Manual
19. GH: A Portable C to Scheme Interface
This chapter shows how to use the GH interface to call Guile from your
application's C code, and to add new Scheme level procedures to Guile
whose behaviour is specified by application specific code written in C.
Note, however, that the GH interface is now deprecated, and developers
are encouraged to switch to using the scm interface instead. Therefore,
for each GH feature, this chapter should also document how to achieve
the same result using the scm interface.
