[algogeeks] Re: Writing C program without main()

Sun, 21 May 2006 10:23:27 -0700

I got the following error when I ran ``ld -e test.o -e f''
where f is a function
------
int f() {
}
------
ld: warning: cannot find entry symbol f; defaulting to 0000000008048094

        I do not know you can do it with out assembly language .

The main() is just an entry to a program, telling the computer to
execute right here.
So if you can tell the CPU in other ways, you can abandon main().
That's why when computer starts, POST will be triggered, CPU just fetch
the first instruction from bios and execute.
