Re: [c-prog] Re: program without main()

[mail . mastermind]

this is because of some of the people claiming so and the kind of
support provied in gcc (and may be turbo C++ will i hate this ancient
compiler )

check link http://livefusion.wordpress.com/2006/08/24/c-program-without-main/

snips. Yes it is possible to write a program in c without using main.

Here is the code:
/* prog_without_main.c */
_start()
{
_exit(my_main());
}

int my_main(void)
{
printf("Hello\n");
return 42;
}

And use this command (% is command prompt) to compile:
%gcc -O3 -nostartfiles prog_without_main.c

Try compiling this example:

#include<stdio.h>

#define decode(s,t,u,m,p,e,d) m##s##u##t
#define begin decode(a,n,i,m,a,t,e)

void begin()
{
printf("hello");

}
