\subsection{API Index}
The above sections describe most everything you need for embedding in
a typical application, notably creating environments and evaluating
code from sexps, strings or files. The following sections expand on
additional macros and utilities for inspecting, accessing and creating
different Scheme types, and for performing port and string I/O.
Being able to convert from C string to sexp, evaluate it, and convert
the result back to a C string forms the basis of the C API. Because
Chibi is aimed primarily at minimal size, there are relatively few
other utilities or helpers. It is expected most high-level code will
be written in Scheme, and most low-level code will be written in pure,
Scheme-agnostic C and wrapped via the FFI.
\subsubsection{Type Predicates}
The sexp represents different Scheme types with the use of tag bits for
