NAME
qinit - STREAMS queue processing procedures structure SYNOPSIS
#include <sys/stream.h> INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI) DESCRIPTION
The qinit structure contains pointers to processing procedures for a QUEUE. The streamtab structure for the module or driver contains pointers to one queue(9S) structure for both upstream and downstream processing. STRUCTURE MEMBERS
int (*qi_putp)(); /* put procedure */ int (*qi_srvp)(); /* service procedure */ int (*qi_qopen)(); /* open procedure */ int (*qi_qclose)(); /* close procedure */ int (*qi_qadmin)(); /* unused */ struct module_info *qi_minfo; /* module parameters */ struct module_stat *qi_mstat; /* module statistics */ SEE ALSO

NAME
put - call a STREAMS put procedure SYNOPSIS
#include <sys/stream.h> #include <sys/ddi.h> void put(queue_t *q, mblk_t *mp); INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI). PARAMETERS
q Pointer to a STREAMS queue. mp Pointer to message block being passed into queue. DESCRIPTION
put() calls the put procedure ( put(9E) entry point) for the STREAMS queue specified by q, passing it the message block referred to by mp. It is typically used by a driver or module to call its own put procedure. CONTEXT
put() can be called from a STREAMS module or driver put or service routine, or from an associated interrupt handler, timeout, bufcall, or esballoc call-back. In the latter cases, the calling code must guarantee the validity of the q argument. Since put() may cause re-entry of the module (as it is intended to do), mutexes or other locks should not be held across calls to it, due to the risk of single-party deadlock (put(9E), putnext(9F), putctl(9F), qreply(9F)). This function is provided as a DDI/DKI conforming replacement for a direct call to a put procedure. SEE ALSO
put(9E), freezestr(9F), putctl(9F), putctl1(9F), putnext(9F), putnextctl(9F), putnextctl1(9F), qprocson(9F), qreply(9F) Writing Device Drivers STREAMS Programming Guide NOTES
The caller cannot have the stream frozen when calling this function. See freezestr(9F). DDI/DKI conforming modules and drivers are no longer permitted to call put procedures directly, but must call through the appropriate STREAMS utility function, for example, put(9E), putnext(9F), putctl(9F), and qreply(9F). This function is provided as a DDI/DKI conforming replacement for a direct call to a put procedure. The put() and putnext() functions should be called only after qprocson() is finished.
