Save Linked-List in binary file

Save Linked-List in binary file - 01/20/12 19:39

Hi, so I have just returned to 3DGS and I'm totally lost now as I'm used to other languages then c.

Now to my question:
I have a struct

Code:

typedef struct INFANTRIST { 
	STRING* Name; 
	long ID;
	ENTITY* ent;
  
  struct INFANTRIST* next;
} INFANTRIST;

As you see it store it in some kind of linked List.
Now I want to save the whole List into a file.
I know how I'd do it with a normal .txt but I prefer binary files for saves.
I know

Code:

file_str_writeto( file_handle, (char*)&x , sizeof(INFANTRIST) );

but it will (obviously) just save the String Pointer, also it won't save the "long ID".

I tried some things but can't get it to work properly.
Any help for a successful comeback to 3DGS would be appreciated

I hate it that I havn't used a c-like language for years, now that my university only uses java mostly

hi,
as a first guess, instead of ENTITY*, its handle should be used for saving somehow. it is said to be the same on every run. but I don't have a ready to use solution... or save the file name of the entity model with the necessary properties (x,y,z, pan,tilt... flags...)

Ja das hatte ich dann sowieso vor.
Ich glaube auch das ich ne L�sung h�tte, falls ich es hinbekommen w�rde einen String mit beliebiger L�nge zu sichern und wieder auszulesen.
Aber da mehrere EIntr�ge mit verschieden langen Strungs gespeichert und gelesen werden sollen, bin ich mir nicht ganz sicher wie ich das Bin�r l�sen kann.
