Detailed Description

This file contains the token encodings. Since tokens are do not a priori have to be a static entity, the encoding can change over time. It is entirely up to the slave to define the token arrangements and internal decoding structure. Changing the token structure will NOT break netpp compatibility.

However, note that there are reserved tokens which can never be used in user space, see devlib_types.h

#define DEVICE_TOKEN

(

x

)

( x << 28 )

'x' = device index

Examples:

slave_test.c.

Typedef Documentation

typedef struct device_desc_t DeviceDesc

This is generated by the XML processor and contains all the necessary information for the device control. It is typically instanced in proplist.c.

typedef struct dyn_prop_t DynPropertyDesc

Needed for parameters changing during the entire netpp session. Currently, we use only Hubs, Ports, and Devices. See ports.h.

Enumeration Type Documentation

enum PNodeType

Enumerator:

DC_HUB	Hub.
DC_PORT	Port.
DC_DEVICE	Device.
