STREAMS Walkers

b_cont

Given the address of an mblk_t, iterate over the set of associated message structures by following the b_cont pointer. The b_cont pointer is used to link a given message block to the next associated message block that is the continuation of the same message. The message block is described in more detail in msgb(9S)

b_next

Given the address of an mblk_t, iterate over the set of associated message structures by following the b_next pointer. The b_next pointer is used to link a given message block to the next associated message block on a given queue. The message block is described in more detail in msgb(9S).

qlink

Given the address of a queue_t structure, walk the list of related queues using the q_link pointer. This structure is defined in <sys/stream.h>.

qnext

Given the address of a queue_t structure, walk the list of related queues using the q_next pointer. This structure is defined in <sys/stream.h>.

readq

Given the address of an stdata_t structure, walk the list of read-side queue structures.

writeq

Given the address of an stdata_t structure, walk the list of write-side queue structures.
