Descriptor Type and Operations

Abstract

packetC provides data types that do not appear in standard C but do provide significant support for packet-processing applications. These data types are often extensions of familiar C types. The extended data type described in this chapter is descriptors. This chapter is divided into two different approaches. The first part of this chapter is focused on simply covering examples of descriptors and the packetC standard include file protocols.ph. The second part of this chapter covers an in-depth view into the background of the descriptors and how they operate under the hood as these are new to packetC.
