Specifies that the point is not on a cell or cell header 指定该点不在单元格或单元格标头。
The cell header is a struct of type rheap : : scell defined as part of the rheap class in e32std . h 内存单元包括一个跟随在单元体后的单元句柄。单元体可以认为是已经分配出去的内存区。
A cell consists of a cell header followed by the body of the cell itself . the body of the cell is the area of memory which is considered allocated 内存单元包括一个跟随在单元体后的单元句柄。单元体可以认为是已经分配出去的内存区。
Many high - speed switch / routers we used today are based on the structure of link card and switch backplane , which have the characteristics of high throughput and flexible port configurations . in such a system , every input variable length packet are segmented into fixed length cells . then the backplane switches the cells to their corresponding output ports based on the information carried by the cell headers 大量的高速交换机/路由器采用线卡结合交换背板的结构,其优势在于较高的系统容量与较灵活的端口配置,即由线卡将输入的变长分组切割为定长的短分组( cell ) ,交换背板对cell进行交换,再在出端口将cell重组为原始的变长分组。
