I setup termios structure with IGNBRK is not set and BRKINT is set.
To allow the process to receive signals I call: fcntl(fd, F_SETOWN, getpid());
I have made a signal handler to catch all signals. I can catch SIGINT when pressing ctrl+c but when I send break signal over serial then it cannot... (13 Replies)

For a program I am designing, which involves handling the keyboard input Ctrl^c (SIGINT), it is taking ages for the program to actually recognise and perform the corresponding action whenever I run it and hit Ctrl^C at the CL. I have to do at least 3 Ctrl^Cs before the program will actually... (3 Replies)
Hi all,
I have this method to read a string from a STDIN:
void readLine(char* inputBuffer){
fgets (inputBuffer, MAX_LINE, stdin);
fflush(stdin);
/* remove '\n' char from string */
if(strlen(inputBuffer) != 0)
inputBuffer = '\0';
}
All work fine but if i... (1 Reply)
I've written a bash script which captures video with DVgrab. Because of the nature of the tapes that I am digitizing, sometimes I want to quit capturing before the time that I set for DVgrab. When this is the case I press Ctrl-c and DVgrab exits cleanly, my problem is that there is additional... (5 Replies)

I have made a very simple script that runs 2 commands, polipo proxy and tor. The script runs successfully and the output of tor is visible to the screen.
I am using the trap command in order to catch the ctrl+c button combo in order to stop polipo... (5 Replies)
Tried to add a function to my control_c interrupt here. It works but has one little bug. If the user selects to run the function instead of exiting, the program restarts itself without forking as it should. However, after that control_c no longer works again. I wanted to allow the user to run... (1 Reply)

kill
KILL(1) General Commands Manual KILL(1)NAME
kill, broke - print commands to kill processes
SYNOPSIS
kill name
broke
DESCRIPTION
Kill prints commands that will cause all processes called name and owned by the current user to be terminated. Use the send command of
81/2(1), or pipe the output of kill into rc(1) to execute the commands.
Kill suggests sending a kill note to the process; the same message delivered to the process's ctl file (see proc(3)) is a surer, if heavy
handed, kill, but is necessary if the offending process is ignoring notes.
Broke prints commands that will cause all processes in the Broken state and owned by the current user to go away. When a process dies
because of an error caught by the system, it may linger in the Broken state to allow examination with a debugger. Executing the commands
printed by broke lets the system reclaim the resources used by the broken processes.
