NAME
select_dequeue - General: Removes the last kernel thread waiting for an event
SYNOPSIS
void select_dequeue(
sel_queue_t *selq );
ARGUMENTS
Specifies a pointer to a sel_queue structure.
DESCRIPTION
The select_dequeue routine removes the last kernel thread waiting for an event to occur on the specified device. This routine is called to
terminate a select call. Typically, a kernel module's xxselect routine calls select_dequeue when the kernel sets the scanning argument (for
the module's xxselect routine) to the value 0 (zero). This value causes the kernel to unblock any kernel threads suspended when selecting
events for this device.
