This section is in limbo. It used to document the 'low-level' C API
of Guile that was used both by clients of libguile and by libguile
itself.
In the future, clients should only need to look into the sections
@ref{Programming in C} and @ref{API Reference}. This section will in
the end only contain stuff about the internals of Guile.

@node Boolean Data
@subsubsection Booleans
Here are functions and macros for operating on booleans.
@deftypefn Macro SCM SCM_BOOL_T
@deftypefnx Macro SCM SCM_BOOL_F
The Scheme true and false values.
@end deftypefn
@deftypefn Macro int SCM_NFALSEP (@var{x})
Convert the Scheme boolean value to a C boolean. Since every object in
Scheme except @code{#f} is true, this amounts to comparing @var{x} to
@code{#f}; hence the name.
@c Noel feels a chill here.
@end deftypefn
@deftypefn Macro SCM SCM_BOOL_NOT (@var{x})
Return the boolean inverse of @var{x}. If @var{x} is not a
Scheme boolean, the result is undefined.
@end deftypefn
Booleans are represented as two specific immediate SCM values,
@code{SCM_BOOL_T} and @code{SCM_BOOL_F}. @xref{Booleans}, for more
information.
