I understand how to include C files in Obj-C programs. But can I do the opposite and add Obj-C files into an existing C program. And if so, how? For my case, I want to add a geometry class to SQLite. I have developed the geometry objects and methods. Now how can I call these files and pass information in the form of C strings from the established SQLite code in C to the Obj-C files and back?
Here is an example:
Typical SQLite C
static int parseHhMmSs(const char *zDate, double *prJD)
-(BOOL)parse:(NSString *)geometryText intoArray:(NSMutableArray *)pointsArray;
How can I call the Obj-C methods from within the SQLite C code (or an Objective-C method from any C code for that matter)?

You should be able to declare the needed ObjC function in a header file and call them directly. extern may be required when declaring the prototypes. [Obviously, all code will need to be compiled with the same compiler.]
