[ubuntu] ejecting cd rom by code

i keep getting the following error code when trying to eject my cd-rom drive, the only way i can get it to eject is by powering off.

Error ejecting: eject exited with exit code 1: eject: unable to eject, last error: Inappropriate ioctl for device

mike@hackbox:~$ eject -rv eject: using default device `cdrom' eject: device name is `cdrom' eject: expanded name is `/dev/cdrom' eject: `/dev/cdrom' is

Hello, I wrote this simple program which prints all the arguments given to a program.

My code is straightforward and this is it

Code: #include <stdio.h> #include <malloc.h>

int i = 0; int main(int argc, char** argv) {  printf("\nargc == [%d]",argc);  printf("\nthe arguments are ");  for(i=0;i<argc;i++)  {   printf(&q

Code of baul :)

A program from apue.

#include "apue.h" #include <fcntl.h>

int main(int argc, char *argv[]) { if(argc!=2) err_quit("usage: a.out <pathname>");

if(access(argv[1], R_OK)<0) err_ret("access error for %s",argv[1]); else printf("read access OK\n"); if (open(argv[1], O_RDONLY)) { err_ret("open error for %s", argv[1]); } else {

Hi All,

I have written a C program to solve this problem but I am eager to know whether the same output can be obtained using sed or awk?

This is the input:

Code: star ferry computer symbol prime time This is the output:

Code: starferry ferrycomputer computersymbol symbolprime primetime

This is my code written in C.

Code: #include<stdio.h> #include<stdlib.h> #includ

Hey, When I type at the shell saying

Code: $./Name_Of_My_Executable this is a list of arguments It goes inside the main as

Code: int main(int argc, char** argv) {

} Who makes sure that the count of arguments goes to int argc and that *argv holds "the" and *(argv+1) holds "is" etc. ?

Is it the the shell itself ?

Thanks.

Trying to compile following code in terminal i got

gcc: -pthread: No such file or directory,

what does this error means and how to eliminate it?

file name: window.c

code:

#include <gtk/gtk.h>

int main(int argc, char *argv[]) {

GtkWidget *window;

gtk_init(&argc, &argv);

window = gtk_window_new(GTK_WINDOW_TOPLEVEL); gtk_widget_show(window);

gtk_main(); return 0;

AIM:to create a copy of file through pipe via two processes

1st process(parent) opens a existing file and reads size and creates a buffer and sends to pipe

2nd process(child) takes the info from pipe and creates annother buffer and writes to new file

what has occurred is a seg fault i tried so severe to find fault but could not find

suggest any code optimization if possible

CODE:
