Well, I know what you mean. Actually, you cant store functions in structs. Thats why they are called structs: "data structures". Though, the developers said, that they will eventually add functions to structs (which seems odd to me, but, well... okay).

As a solution, you can save a function ptr into an instance of a struct. By this you could write your own routine to execute those functions by passing their pointer which is saved inside the instance.



Yes I know you can do that somehow, but not how exactly. I tried looking for it in the manual, but without success. Also looked in that online book you linked too, which indeed explains how to do it in C. However, when I tried doing it in lite-c, it would complain about syntax errors. I tried having these declarations inside a struct:

Code:
function (*myfunk);
function (*myfunk)();
function (*myfunk)(void);
int (*myfunk);
int (*myfunk)();
int (*myfunk)(void);


Only one at the time of course to try it out. None of the above was allowed.

There are good examples in the manual - try them first!



I dont think you understood what I meant. I know how to use them, not how they work. Exactly what do they return? Usually, you'd have to do something like this:

member of struct equals something/function return value
i.e. for example

Code:
PANEL* my_panel =
{
pos_x = 10;
pos_y = func_that_returns_a_var();
}


But then we have these string() and digits(), which you dont use in that way. You just invoke them inside an object initialization:

Code:
PANEL* my_panel =
{
digits(10,10,2,*,1,some_var);
}


Why exactly is that allowed? Is it possible for me to define a function that is allowed within an object initialization like that?

Quote:

Code:
typedef struct TRACKPOINT {
	VECTOR pos;
	struct TRACKPOINT *parent, *child;
} TRACKPOINT;


which saves a vector and two pointers two other instances. As you can see, you can only store data.



About that. Are there any data structures implemented in lite-c already? Kinda like STL in C++ so you wont have to implement your own vectors, lists and maps?
