I can use add_struct() to mark an area of dynamically allocated memory that will then be saved when calling game_save()with SV_STRUCT.

My question is, once i have marked an area with add_struct, is there any way to unmark it? (say i allocate an area of memory to store an object, then that object is destroyed in game, so i release the memory). If there is no way to un-mark the memory, what happens when i have game_save() save an area of memeory that is no longer valid?

Another thing i thought of, if i have the following code:

typedef struct my_struct1
{ var my_var1;
var my_var2;
} my_struct1

typedef struct my_struct2
{ my_var3;
my_var4;
} my_struct2;

typedef struct my_struct3
{ my_var5;
my_var6;
my_struct1* struct1_ptr;
my_struct2* struct2_ptr;
struct my_struct3* next;
}

In order for game_save to save the *entire* my_struct3, i would have to do an add_struct for each of the structs, IE:

add_struct(my_struct3_ptr,sizeof(my_struct3));
add_struct(my_struct2_ptr,sizeof(my_struct2));
add_struct(my_struct1_ptr,sizeof(my_struct1));

is this correct?
