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) Writing Device Drivers STREAMS Programming Guide NOTES
The caller may not have the STREAM frozen during either of these calls. SunOS 5.10 11 Nov 1992 qprocson(9F)
