Auto-recursive main() function
"Give me a place to stand and a lever long enough and I will move the
world !" -- Archimedes
I prove that it is possible to write a recursive (auto-recursive) main()
function, that is : we do not need to call another function from main()
to recurse ourselves.
In the technicals of it, we must use both of the first 2 arguments of
the main(argc, argv) function.
A external pointer must be used, so we can append to it some value that
must be externalised.
#include <stdio.h>
int *addr;
int main(int argc, char *argv[])
{
addr = & argc;
++(*addr);
printf("Hello, world\n");
return (argc < 10) ? main(argc, argv) : 0;
}
PS : imi pot imagina si alte utilizari, precum _start() /
_start_kernel() din Linux booting process,
punand la printk() ca argument un fisier .txt, obtinut dintr-o poza kewl
(vezi Linux T-shirt, May the source be with you,
ori Christmas Tree .c/.txt in kernel, ori o poza cu o domnisoara draguta
din vacanta de la mare ;-) , de preferinta prietena :-) ), poza trecuta
prin Jpeg2Ascii, aflat in Ubuntu, Debian si celelalte distributii,
precum si pe Net ca packet independent. Amin.
