BLK_STACK_LIMITS(9)						   Block Devices					       BLK_STACK_LIMITS(9)

NAME

       blk_stack_limits - adjust queue_limits for stacked devices

SYNOPSIS

       int blk_stack_limits(struct queue_limits * t, struct queue_limits * b, sector_t start);

ARGUMENTS

       t
	   the stacking driver limits (top device)

       b
	   the underlying queue limits (bottom, component device)

       start
	   first data sector within component device

DESCRIPTION

       This function is used by stacking drivers like MD and DM to ensure that all component devices have compatible block sizes and alignments.
       The stacking driver must provide a queue_limits struct (top) and then iteratively call the stacking function for all component (bottom)
       devices. The stacking function will attempt to combine the values and ensure proper alignment.

       Returns 0 if the top and bottom queue_limits are compatible. The top device's block sizes and alignment offsets may be adjusted to ensure
       alignment with the bottom device. If no compatible sizes and alignments exist, -1 is returned and the resulting top queue_limits will have
       the misaligned flag set to indicate that the alignment_offset is undefined.

NAME

       Tk_RestackWindow - Change a window's position in the stacking order

SYNOPSIS

       #include <tk.h>

       int
       Tk_RestackWindow(tkwin, aboveBelow, other)

ARGUMENTS

       Tk_Window tkwin (in)		  Token for window to restack.

       int aboveBelow (in)		  Indicates new position of tkwin relative to other; must be Above or Below.

       Tk_Window other (in)		  Tkwin  will be repositioned just above or below this window.	Must be a sibling of tkwin or a descendant
					  of a sibling.  If NULL then tkwin is restacked above or below all siblings.
_________________________________________________________________

DESCRIPTION

       Tk_RestackWindow changes the stacking order of window relative to its siblings.	If other is specified as NULL then window is  repositioned
       at  the	top or bottom of its stacking order, depending on whether aboveBelow is Above or Below.  If other has a non-NULL value then window
       is repositioned just above or below other.

       The aboveBelow argument must have one of the symbolic values Above or Below.  Both  of  these  values  are  defined  by	the  include  file
       <X11/Xlib.h>.
