cpp70.sdl

Schema for the cpp70Example_main.cpp example. Compile this schema using rdm-compile as follows:

rdm-compile --c-structs --lc-struct-members --catalog cpp70.sdl

and include the generated header file(s) as follows:

#include "cpp70_structs.h"
#include "cpp70_cat.h"

and compile the following generated source file(s):

cpp70_cat.c

Here follows the actual schema:

/*
 * EXAMPLE - CPP70 for CPP using the C core API and Time Series C++ 
 *
 * This is the DDL (Database Definition Language) for a single field,
 * single record-type database. The one record type is called CORE03_RECORD,
 * and it's one field, MESSAGE, can store an UTF-8 string.
