-/****************************************************************
- In order to make use of the GENERIC_LIST data structure, you
- should create wrapper functions around:
-
- BOOL generic_list_insert()
- void* generic_list_remove()
- void* generic_list_locate()
-
- The reason this is necessary is that the GENERIC_LIST uses a
- void pointer to store your data structure. This means that
- you get no type checking and can create a heterogenous list.
- However, you will need to have some way to determine the type
- of your data. If you are using a homogenous list, then
- wrapper functions are the easiest way. If you are creating
- a heterogenous list, then you will need to use the type field
- for your arbitrary identifiers.
-
- TODO:
- If necessary, you can add a few generic_list_*() to do things
- like grab from the front (to implement a FIFO queue) or from
- the tail (to implement a FILO stack)
