We must not ignore small problems, because they eventually grow big.
how to fork
Written by georg on Oktober 31, 2008
Ich glaub ich hab gerade meinen ersten Prozess unter C geforkt. Auch wenn der Beispielcode nichts sinnvolles tut 😉
Die simple Frage war, was hier vom Parent ausgegeben wird. Recht offensichtlich (und durch ausprobieren rauszufinden ist die Lösung wohl 5!
#include <sys/types.h>
#include <stdio.h>
#include <unistd.h>
int value = 5;
int main()
{
pid_t pid;
pid = fork();
if (pid == 0) { /* child process */
value +=15;
}
else if (pid > 0) { /* parent process */
wait (NULL);
printf("PARENT: value = %d",value);
}
}

The UNIX system has a command, nice, which allows a user to voluntarily reduce the priority of his process, in order to be nice to the other users. Nobody ever uses it.
