bakunin,
Thanks for the explanation. I know what array bounds checking means. That's why I posted this question. Have you tried turning on the -Warray-bounds on GCC and accessing an illegal array position to see if it works as you described? I was expecting the compiler will give me warning for accessing an array element beyond its declared size, but it didn't give me any warnings at all. The below program runs just fine on my Linux box. I gave the gcc version on my post above. If I assign 10000 to index, program give segmentation fault, but still compiles with no warnings. -Warray-bounds switch is on.
:confused: I have a question concerning gcc. IŽd like to install the gcc on my Mac OS X, but when I try to run the configure command I get the following message:

Hi,
we are converting from IBM-AIX(xl c/c++ compiler) to Linux(GCC complier).
As a part of this i need to change the CFLAGS.
The xl c/c++ complier CFLAGS is
CFLAGS := $(CDEBUG) $(PROJECT_INCLUDE_DIRS) $(COBJECT_MODE) -qcpluscmt -qmakedep -qcheck=all \

It might be a simple one but I have this question bothering me for sometime.
When we do a symbol search inside the library directory (i.e. /usr/lib/*) via tools like nm; it takes a while to give us the results. However, its very quick when gcc is invoked to compile a program with the very same... (11 Replies)

XkbComputeShapeBounds(3) XKB FUNCTIONS XkbComputeShapeBounds(3)NAME
XkbComputeShapeBounds - Updates the bounding box of a shape
SYNOPSIS
Bool XkbComputeShapeBounds ( shape )
XkbShapePtr shape;
ARGUMENTS
- shape
shape to be examined
DESCRIPTION
Xkb provides a number of convenience functions to help use a keyboard geometry. These include functions to return the bounding box of a
shape's top surface and to update the bounding box of a shape row or section.
A shape is made up of a number of outlines. Each outline is a polygon made up of a number of points. The bounding box of a shape is a rec-
tangle that contains all the outlines of that shape.
A ShapeRec contains a BoundsRec that describes the bounds of the shape. If you add or delete an outline to or from a shape, the bounding
box must be updated.
XkbComputeShapeBounds updates the BoundsRec contained in the shape by examining all the outlines of the shape and setting the BoundsRec to
the minimum x and minimum y, and maximum x and maximum y values found in those outlines. XkbComputeShapeBounds returns False if shape is
NULL or if there are no outlines for the shape; otherwise, it returns True.
If you add or delete a key to or from a row, or if you update the shape of one of the keys in that row, you may need to update the bounding
box of that row. To update the bounding box of a row, use XkbComputeRowBounds.
STRUCTURES
typedef struct _XkbShape {
Atom name; /* shape's name */
unsigned short num_outlines; /* number of outlines for the shape */
unsigned short sz_outlines; /* size of the outlines array */
XkbOutlinePtr outlines; /* array of outlines for the shape */
XkbOutlinePtr approx; /* pointer into the array to the approximating outline */
XkbOutlinePtr primary; /* pointer into the array to the primary outline */
XkbBoundsRec bounds; /* bounding box for the shape; encompasses all outlines */
} XkbShapeRec, *XkbShapePtr;
typedef struct _XkbBounds {
short x1,y1; /* upper left corner of the bounds, in mm/10 */
short x2,y2; /* lower right corner of the bounds, in mm/10 */
} XkbBoundsRec, *XkbBoundsPtr;
