#include <sys/stream.h> #include <sys/ddi.h> void qunbufcall(queue_t *q, bufcall_id_t id);
The qunbufcall() function is tailored to be used with the enhanced STREAMS framework interface which is based on the concept of perimeters. (See mt-streams(9F).) qunbufcall() returns when the bufcall has been cancelled or finished executing. The bufcall will be cancelled even if it is blocked at the perimeters associated with the queue. All outstanding timeouts and bufcalls must be cancelled before a driver close routine can block and before the close routine calls qprocsoff(9F).
