I have a few new structures that I have created. This would be my first time adding them to the CHAR and PC_DATA structures.
In these structures I have a linked list. When I remove one of them I just set it to NULL, such as: ch->structure_here = NULL; I am not sure if this is enough, as the structure contains 5 or 6 fields of data. I suspect that the data is still there, but the pointer doesn't point to it. This then would increase memory over time. So, you have to free it first with a function, such as: free_structure_here(ch->structure_here); then set it to NULL. ch->structure_here = NULL; Is this correct? Or does just setting the pointer to NULL do enough? When I add to the linked list, I do this: STRUCTURE_HERE *blah = new_structure(); Where in new_structure it has: struct = alloc_perm( sizeof(*struct) ); Thank you.
