DO NOT EDIT. This file is generated automatically.
This is an amalgamated single-header version of the library.
INSTRUCTIONS:
- Include at will in any header of your project
- In one (and only one) of your project source files,
#define {defmacro} and then include this header.
This will enable the function and class definitions in
the header file.
- To compile into a shared library, just define the
preprocessor symbol C4CORE_SHARED . This will take
care of symbol export/import.
