I snipped a lot of this discussion. Seems to be wandering
off-topic'ish/flame'ish.
Rick, you could do what I did. If you have an existing C base, many of
C++'s _concepts_ are adaptable to C. For instance, classes. In C++,
you do:
class MyClass
{
public:
MyClass();
~MyClass();
int SomeFunc();
private:
int SomeVar;
char *AnotherVar;
};
In C, you could translate that to:
struct MyClass
{
int SomeVar;
char *AnotherVar;
};
struct MyClass *CreateMyClass()
{
// Allocate a structure and pre-fill the fields.
}
int DestroyMyClass(struct MyClass *MainPtr)
{
// Deallocate the structure.
}
int SomeFunc(struct MyClass *MainPtr)
{
// Perform some action and return result.
}
(I know I used C++-style comments. Habit. Sorry.)
You get the idea. I just took a C++ idea and implemented it in C. Yes,
it results in more code and uses an unprotected struct, but back when I
started using the above OOP-style concept, C++ compilers weren't exactly
around. Moving to C++ for me was a natural move once I determined that
C++ compilers had stabilized sufficiently.
