NAME
RD - STREAMS: Gets a pointer to a module's read queue
SYNOPSIS
#include <sys/stream.h>
queue_t * RD(
queue_t *queue_pointer );
ARGUMENTS
Specifies a pointer to the write queue whose read queue is to be returned. The typedef queue_t is an alternate name for struct queue_entry
*.
DESCRIPTION
The RD interface accepts a write queue pointer as an argument and returns a pointer to the read queue of the same module.
CAUTIONS
Make sure the queue_pointer argument is a pointer to a write queue. The RD interface does not check for queue type. A system panic could
occur if queue_pointer is not a write queue.
RETURN VALUES
Upon successful completion, RD returns the pointer to the read queue.
