Hi!
What is a bus master device?
-------------------------------------------------------------
what is the difference between real, protected and virtual v86 mode, and
where and why are these respective modes used?
-------------------------------------------------------------
What is happening here ? :
static int foo P((void));
/* code */
static int foo()
{
/* code
*/
}
what is the meaning of the P((void)). Why doesn't he just do static int
foo(); there ?
-------------------------------------------------------------
I)
What is an AVL tree? Any special advantages?
-------------------------------------------------------------
II)
WHat is a reentrant function?
-------------------------------------------------------------
III)
I have seen in many programmes the following code :
foo(int *iptr)
{
int j;
j = ptr;
}
ok, forget the cast for now, this is slightly tricky if sizeof(int) !=
sizeof(*) on some architectures.
fine. but why doesn't the guy just say int *iptr2 = iptr1 in the above
code.
Is it a performance eenhancement to equate it to int rahter then a pointr
in th e fucnntion ?
Mind you, he uses it as a pointer(i.e. j) in the code after the
assignment.
Thanks for any replies . :-)
