Typedef Documentation

EDS_fwHandlerCfgs

Typedef for struct _EDS_fwHandlerCfgs.

This structure is initialized when a handler is installed and updated by the EDS_fwSelect routine.

EDS_fwLists

Typedef for struct _EDS_fwLists.

Many of the actions of the framework are performed over sets and subsets of the registered callbacks. Some of these lists are static, that is they are determined during registration, and some are dynamic, that is they are constructed as the event and its possible subpackets are processed. This structure collects these list in one spot

EDS_fwMem

Typedef for struct _EDS_fwMem.

The memory allocator can be made a part of the framework routines. In general, the system allocators, malloc and free would be adequate. However, on the embedded systems, these draw from the limit system pool. This was not considered acceptable. So, the only alternative was to make the memory management available via callbacks

EDS_fwPktFree

Typedef for struct EDS_fwPktFree.

This framework is built to run with a variety of event feeders. The principle one is LCBD, but file based feeders are also used. Because of this and because the LCBD routines cannot be directly linked into these routines (they get exported to the offline world, where a real LCB is non-existent), they freeing of a packet is done via a callback.
