streamtab(9S)

The streamtab(9S) structure contains pointers to the structures that hold the routines that actually initialize the reading and writing for module.

If streamtab is NULL, it signifies no STREAMS routines and the entire driver is treated as though it were a regular driver. The streamtab(9S) indirectly identifies the appropriate open, close, put, service, and administration routines. These driver and module routines should generally be declared static.

struct streamtab {
		struct qinit		*st_rdinit;			/* defines read queue */
		struct qinit		*st_wrinit;			/* defines write queue */
		struct qinit		*st_muxrinit;		/* for multiplexing */
		struct qinit		*st_muxwinit;		/* drivers only */
};
