NAME
       select_enqueue - General: Adds the current kernel thread

SYNOPSIS
       void select_enqueue(
	       sel_queue_t *selq );

ARGUMENTS
       Specifies a pointer to a sel_queue structure.

DESCRIPTION
       The select_enqueue routine adds the current kernel thread to the list of kernel threads waiting for a select event on the specified device.
       This routine is called when a kernel module's select routine has been called and the requested event cannot be immediately satisfied.   For
       example,  the  requested  event	cannot	be immediately satisfied when xxselect is called for the following reasons: To select on input and
       there are no characters available When called for output and the kernel module's output buffers are currently full

       By calling select_enqueue, the kernel module's select routine ensures that the kernel thread issuing the select call will be blocked  until
       the requested event can be satisfied or until the select call terminates.

CAUTIONS
       You must call the queue_init routine to initialize the sel_queue structure pointer prior to calling select_enqueue. Failure to do so causes
       the kernel to panic.

RETURN VALUES
       None
