Data Structures

Feature List Structure

When an application calls TELOtherFeatureList to get a list of network-switch features that can be accessed without passing any tool-specific parameters, the telephone tool returns a pointer to a linked list of feature list structures that describe those features. The feature list structure is defined by the FeatureList data type.

struct FeatureList {
   short                   featureID;
   StringPtr               featureName;
   short                   handleType;
   struct FeatureList      *nextFeature;
};
typedef struct FeatureList FeatureList;
typedef FeatureList *FeatureListPtr;

Field Description

featureID

A tool-defined value that identifies the feature.

featureName

A pointer to the name associated with the feature.

handleType

The type of handle you must access when implementing the feature. See "Handle Types" on page 1-23 for a description of the available handle types.

nextFeature

A pointer to the next item in the feature list. A nil value indicates that there are no more features.
