/prog/ - So today I wrote my first program

Name: Anonymous 2010-09-22 4:40



#include <stdio.h>

#include <stdlib.h>

int main(void)

{

 return (printf("hello, world") < 0) ? EXIT_FAILURE : EXIT_SUCCESS;

}

My teacher said that I shouldn't program at all. What the fuck?

no exceptions

i have to agree. why are you including stdlib.h? knock it off with that EXIT_SUCCESS faggotry and use a literal 0. it's clearer that way. also don't bother checking for failures when writing to stdout. if your writes to stdout are failing, you're fucked no matter what you do. your program will be cleaner without the extra code

Unspecified return values are clearer than specified ones? My goodness, perhaps you shouldn't program at all either?

what system do you program that doesn't indicate success with 0 and failure with anything besides 0?

I have heard that many system calls (mostly obscure ones though, like sys_read, sys_write) return positive values as success.

Most functions tend to do that. It's intuitive in a conditional statement. Programs, however, usually do the opposite.

functions do that. not program exit codes. so for every syscall do you #define new status codes? you sound like the type of retard that would #define ONE 1 and #define ZERO 0.

also did you just imply that the read and write syscalls are obscure? what the fuck am i reading?

when your kernel runs a program, what is the first function it calls? is it open()? if it is then i'd like to know the name of your kernel. most kernels however call main()

what about grep

what about grep?
echo a | grep a > /dev/null && echo success

Actually, it calls _start.

it returns 1 on no match

echo a | grep a > /dev/null && echo $? echo a | grep b > /dev/null && echo $?

that is an os- and linker-specific detail. given that the discussion is about main()'s interface, it's reasonable to ignore those things. still i suppose an os's version of _start could invert the value returned by main(), but no one has yet named such a system

Oh wait...
echo a | grep b > /dev/null ; echo $?

yeah, so? grep failed in finding a match, so it returned 1. when it succeeds in finding a match, it returns 0. just like every other program

it's called a return code for a reason. it's not necessarily an error code

pardon me for attempting to get to the root of a misunderstanding. i'm sure the guy with the grep question didn't actually want an informative answer
