I am trying to use AllocRemember/FreeRemember to keep track of all the
resources that I allocate, but it does not seem to work properly. Here
is what I have .
In the main function in one file I have ...
struct Remember *resources = (struct Remember*)NULL;
In a second file, I have the following:
extern struct Remember *resources;
.....
tgad = AllocRemember( resources, sizeof(struct Gadget), MEMF_CHIP );
In a third file:
extern struct Remember *resources;
......
if (resources)
{
printf("memory freed\n");
FreeRemember( resources, TRUE );
}
The printf never gets executed so the memory is not freed. The only
memory I allocate is for eight gadgets (as in above call). The system
loses 512 bytes each time. I am new to these functions and would
appreciate any help as to what I am doing wrong. Thank You.

AllocRemember and FreeRemember take **Remember structure pointers
so your calls should read AllocRemember(&resources,...) and
FreeRemember(&resources,...)

Also this same feature is the cause of much low memory stomping.
Essentially, when used in correctly, these routines use location
0 for their pointer storage. Some fun no?
