The putbq interface places a message at the beginning of the appropriate section of the message queue. There are always sections for high priority and ordinary messages. If other priority bands are us...
The putctl interface tests the type argument to make sure a data type was not specified. It then attempts to allocate a message block. The putctl interface fails if a message block cannot be allocated...
Like the putctl interface, the putctl1 interface tests the type argument to make sure a data type was not specified. It then attempts to allocate a message block. In addition, the putctl1 interface ca...
The putq interface puts a message on a driver's queue after the module's put interface has finished processing the message. The putq interface places the message after any other messages of the same...
The qenable interface puts the queue associated with the queue_pointer argument on the linked list of those whose service interfaces are ready to be called by the STREAMS scheduler.
The qreply interface sends a message on a stream in the opposite direction from the queue specified in the queue_pointer argument. It calls the OTHERQ interface to find the queue's module partner.
The queue_init routine initializes the specified queue. Kernel modules call this routine prior to calling select_enqueue to initialize the links member of the sel_queue data structure. This member spe...
The register_callback routine registers a kernel module's callback routine. The kernel calls a kernel module's callback routine when execution reaches the point specified in the point and order argu...
The insque routine adds the element that the elem argument specifies to the queue. The routine inserts elem in the next position after pred in the queue. The remque routine removes the element that th...
The rmalloc routine allocates size units from the given resource map. In a map, the addresses are increasing, and the list is terminated by a zero size. The actual units managed by the map are arbitra...
The rmfree routine frees the space previously allocated with a call to rmalloc. It frees a space of the size specified by the size argument at the address specified by the addr argument.
