Queue Header

Queue Header

The queue header area contains the descriptor block for all the ZCOM subsystem queues. The first queue is used to link the free buffers in the buffer pool.

Queue Header n

Free Queue Header (zfqh_type), queue 0, basically is the same as the other buffer queues. However, its fields are viewed and used slightly differently from the other queues. Its size is the same as a buffer queue.
