qinit

The qinit(9S) structure (also shown in Appendix A) contains pointers to the STREAMS entry points. These routines are called by the module-loading code in the kernel.

struct qinit {
 	int         (*qi_putp)();            /* put procedure */
 	int         (*qi_srvp)();            /* service procedure */
 	int         (*qi_qopen)();           /* called on each open or push*/
 	int         (*qi_qclose)();          /* called on last close or pop*/
 	int         (*qi_qadmin)();          /* reserved for future use */
 	struct module_info     *qi_minfo;    /* info struct */
 	struct module_stat     *qi_mstat;    /* stats struct (opt)*/
};
