Architecture independent level 1 (DDI/DKI).
The RD() function accepts a write queue pointer as an argument and returns a pointer to the read queue of the same module.
CAUTION: Make sure the argument to this function is a pointer to a write queue. RD() will not check for queue type, and a system panic could result if it is not the right type.
The pointer to the read queue.
The RD() function can be called from user, interrupt, or kernel context.
See the qreply(9F) function page for an example of RD().
