Single-File Library
===================
fixedptc is intended to be simple to use and integrate in other simple
programs, thus is it implemented as a C header-only library. By default, all
functions are inlined. This makes the library easy to use, but can result in a
significant increase in code size for the final executable compared to
a separately-compiled library.
Separate Compilation
====================
If the complex functions are used often in the end-program, the library should
be implemented in a separate C file. To do so:
1. Create a new C file with the text:
#define FIXEDPTC_IMPLEMENTATION
#include "fixedptc.h"
2. Add the new C file to be linked into your project.
3. In each file that uses fixedptc.h,
#define FIXEDPTC_EXTERN
#include "fixedptc.h"
EXPORT_SYMBOL
=============
If an EXPORT_SYMBOL macro is defined before the #include that pulls in the
implementation of fixedptc (FIXEDPTC_IMPLEMENTATION), that macro will be
invoked for each fixedpt function as:
EXPORT_SYMBOL(function_name);
This feature is designed to ease integration with the Linux kernel.
