Mixing Scheme 48 and C
Mike Sperber and Richard Kelsey

This chapter describes an interface for calling C functions from Scheme, calling Scheme functions from C, and allocating storage in the Scheme heap.. Scheme 48 manages stub functions in C that negotiate between the calling conventions of Scheme and C and the memory allocation policies of both worlds. No stub generator is available yet, but writing stubs is a straightforward task.
