Is a null statement a null pointer?
Infrequently Asked Questions in comp.lang.cNo. A null pointer is a pointer where all of the address bits are zero (no matter what the segment bits are), and can be obtained by typing '(char *) (int) 0'.

How will Pointer be maintained?
FAQ PointerThe Pointer Project is aiming to manage the full life cycle of an address through the development of an integrated address maintenance system involving OSNI, VLA, Royal Mail and Local Councils in Northern Ireland. This will ultimately result in the development of proposals for a 'cradle to grave' integrated address life cycle which will aim to maximise automation of the life cycle of an address and minimise manual intervention.
Can I move the mouse pointer myself?
Frequently Asked QuestionsThere is an Xlib routine called XWarpPointer() that does this, but GDK does not wrap it. It is almost certainly a bad idea to use this feature (in fact it is intended for window managers only); you might consider writing to one of the GTK+ or Gnome mailing lists to ask for another way to achieve whatever you are trying to achieve. However, you can always use Xlib routines (such as XWarpPointer()) by including gdk/gdkx.h and gdk/gdkprivate.
Then why are array and pointer declarations interchangeable as function formal parameters?
Infrequently Asked Questions in comp.lang.cClassism. We consider arrays ''second class objects''. They don't vote, and they get treated as pointers. Additionally, they're merely objects, not citizens. Marx wrote about this a lot. [a]
Q#11.9: How do I get the file descriptor from a stdio FILE pointer?

The proper macro definition for the ORCA/C headers is: #define fileno(p) ((p)->_file) Q#11.10: My (ported) source requires <sys/file.h>. Why isn't it there? A#11.10: <sys/file.h> has been superceded by <sys/fcntl.h>. Update your sources. Q#11.11: Why, when I '#include <types.
How do I get a Button to actively change under my mouse pointer?
comp.lang.perl.tk FAQYou should specify both an '-image' and an '-activeimage' configuration option either when calling the ->Button() method or in a later separate call to the ->configure() method.

Why does some code carefully cast the values returned by malloc to the pointer type being allocated?
Infrequently Asked Questions in comp.lang.cIn interrupt-riddled code, it may be necessary to cast values to force the CPU to resolve pointer types. [a]
How do I declare a pointer to an array?
Arrays and PointersUsually, you don't want to. When people speak casually of a pointer to an array, they usually mean a pointer to its first element. Instead of a pointer to an array, consider using a pointer to one of the array's elements. Arrays of type T decay into pointers to type T (see question 6.3), which is convenient; subscripting or incrementing the resultant pointer will access the individual members of the array.
