Summary

Defines the descriptor control for linked list operation.

Description

This data type defines the descriptor control for linked list operation. Descriptor control always applies to the next descriptor in the chain. That is, descriptor control parameters defined in descriptor 'n' applies to the transfer of descriptor "n+1".
