Hi Thomas,
Maybe setsid() should not be called if fork() fails...
Could you try this please:
if (daemonize && !isatty(0)) {
int pid = fork();
if (pid > 0) exit(0); // exit parent process
if (pid == 0) setsid(); // detach child process
if (pid < 0) {
error("could not detach from caller");
exit(9);
}
}
Hint: source code of setsid.c -- util-linux package)
... or maybe the parent thread should not exit immediately but wait:
if (daemonize && !isatty(0)) {
#include <sys/wait.h>
int status;
int pid = fork();
if (pid > 0) {
waitpid(pid, &status, 0);
exit(0);
}
setsid();
}
Can you please try both alternatives?
Thomas
