Summary

This chapter introduced the interface between the Objective CAML language and the C language. This interface allows C functions to operate on Objective CAML values. Using abstract Objective CAML types, the converse is also possible. An important feature of this interface is the ability to use the Objective CAML garbage collector to perform automatic reclamation of values created in C. This interface supports the combination, in the same program, of components developed in the two languages. Finally, Objective CAML exceptions can be raised and (with some limitations) handled from C.
