NAME    [Toc]    [Back]

       RD - STREAMS: Gets a pointer to a module's read queue

SYNOPSIS    [Toc]    [Back]

       #include <sys/stream.h>

       queue_t * RD(
               queue_t *queue_pointer );

ARGUMENTS    [Toc]    [Back]

       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    [Toc]    [Back]

       The RD interface accepts a write queue pointer as an argument
 and returns a pointer to the read queue of  the  same

CAUTIONS    [Toc]    [Back]

       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    [Toc]    [Back]

       Upon successful completion, RD returns the pointer to  the
       read queue.
