qprocson

qprocson(9F)						   Kernel Functions for Drivers 					      qprocson(9F)

NAME

       qprocson, qprocsoff - enable, disable put and service routines

SYNOPSIS

       #include <sys/stream.h>
       #include <sys/ddi.h>

       void qprocson(queue_t *q);

       void qprocsoff(queue_t *q);

INTERFACE LEVEL

       Architecture independent level 1 (DDI/DKI).

PARAMETERS

       q	Pointer to the RD side of a STREAMS queue pair.

DESCRIPTION

       qprocson() enables the put and service routines of the driver or module whose read queue is pointed to by q.  Threads cannot enter the mod-
       ule instance through the put and service routines while they are disabled.

       qprocson() must be called by the open routine of a driver or module before returning, and after any initialization necessary for the proper
       functioning of the put and service routines.

       qprocson() must be called before calling put(9F), putnext(9F), qbufcall(9F), qtimeout(9F), qwait(9F), or qwait_sig(9F).

       qprocsoff() must be called by the close routine of a driver or module before returning, and before deallocating any resources necessary for
       the proper functioning of the put and service routines. It also removes the queue's service routines from the  service  queue,  and  blocks
       until any pending service processing completes.

       The  module  or driver instance is guaranteed to be single-threaded before qprocson() is called and after qprocsoff() is called, except for
       threads executing asynchronous events such as interrupt handlers and callbacks, which must be handled separately.

CONTEXT

       These routines can be called from user or interrupt context.

SEE ALSO

       close(9E), open(9E), put(9E), srv(9E), put(9F), putnext(9F), qbufcall(9F), qtimeout(9F), qwait(9F), qwait_sig(9F)
