The dupmsg interface forms a new message by copying the message block descriptors pointed to by the message_block_ptr argument and linking them. The dupmsg interface calls dupb for each message block....
The enableok interface allows the queue associated with the queue_pointer argument to be rescheduled for service. The interface cancels the effect of a previous call to the noenable interface on the q...
The esballoc interface creates a STREAMS message and attaches a user-supplied data buffer in place of a STREAMS data buffer. The interface calls allocb to obtain a message and data block header. The u...
The ffs routine returns the bit position of the first bit you set in the mask argument. The scan proceeds from the least significant bit to the most significant bit of the mask.
The flushband interface flushes messages associated with the priority band specified by the pri argument. If pri is zero (0), flushband flushes only normal and high priority messages. Otherwise, flush...
The flushq interface frees messages and their associated data structures by calling the freemsg interface. If the queue's count falls below the low-water mark and the QWANTW bit is set, flushq enable...
The freeb interface deallocates a message block. If the reference count of the db_ref member of the datab structure is greater than the value 1, freeb decrements the count. If db_ref equals the value ...
The freemsg interface calls the freeb interface to free all message and data blocks associated with the message pointed to by the message_block_ptr argument.
The getnewbuf routine allocates a buf structure for performing I/O operations. This routine guarantees that the members of the structure are properly initialized prior to initiating the I/O request. D...
The getq interface is used by a service interface to retrieve its enqueued messages. A module or driver may include a service interface to process enqueued messages. Once the STREAMS scheduler calls t...
