23.3.2.7.2 Data Entry

A data entry queue contains data entries of the type shown in Table 23-10. These entries are organized in

a linked list. The first entry of the queue is pointed to by the pCurrEntry field of the queue structure (see

Table 23-9). Each pNextEntry field points to the next entry. The last entry in the queue is also pointed to

by the pLastEntry field of the queue structure.
