Hello, Raghu.
I have found that correct spelling, grammar and punctuation often
prevent misunderstandings. I urge you to avoid abbreviations such as
"wats" and "thanx".
To declare an array of *pointers to* functions taking a single int and
returning void, do something like this:
void a(int);
void b(int);
void (*array_of_poitner_to_func[])(int ) = { a, b };
By the way, I used the "cdecl" and "gcc -Wall -pedantic -ansi" programs
to help me answer your question. If you have access to them, each of
them is a great resource.
You should never have to specify printf's prototype in your program. In
fact, you must never specify printf's prototype in your program. (This
restriction may be technically incorrect. I'm sure someone will correct
me.) Always provide the following line:
#include <stdio.h>
in any program that invokes printf(). Having said that, printf's
prototype is one of these, depending upon which version of C you are using:
int printf(const char * restrict format, ...); /* C99 */
int printf(const char * format, ...); /* C90 */
I found this information in the publicly-available *draft* C99 standard
here:
http://www.open-std.org/jtc1/sc22/wg...69/n869.txt.gz
Note that this draft varies somewhere from the final, published standard.
Finally, please read the FAQ for this newsgroup. You can find it by
specifying "comp.lang.c FAQ" at
www.google.com.
I hope this helps.
