qprocsoff(9f)
qprocson(9F) Kernel Functions 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
The qprocson() enables the put and service routines of the driver or
module whose read queue is pointed to by q. Threads cannot enter the
module instance through the put and service routines while they are
disabled.
The qprocson() function 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.
The qprocson() function must be called before calling put(9F), put‐
next(9F), qbufcall(9F), qtimeout(9F), qwait(9F), or qwait_sig(9F).
The qprocsoff() function 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, interrupt, or kernel context.
