What am I doing wrong? The following program:
#include <signal.h> #include <sys/wait.h> main(){ for(;;) { if( !fork() ) { exit(0); /* child, exit immediately */ } sleep(1); } }
when run with PID=8704 creates children that stay undead until the parent process terminates, e.g. from "ps -x":
You need to wait() on the children (from the parent) to reap them. Otherwise they stay around so that the parent can grab their exit status.
