NAME

xt_daemonize() - Detach process from terminal

LIBRARY

#include <xtend/proc.h>
-lxtend

SYNOPSIS

int     xt_daemonize(int nochdir, int noclose)

ARGUMENTS

nochdir:    If true (non-zero), do not chdir("/")
noclose:    If true, do not redirect standard descriptors to /dev/null

DESCRIPTION

Daemonize a process, using the double-fork() method to ensure that it cannot attach to a controlling tty (terminal). The interface is identical to the BSD daemon(3) function, but daemon(3) only performs a single fork, so there is a risk that the resulting process could attach to a termimal.

The double-fork() entails additional overhead compared to daemon(3), but ensures that the process cannot aquire a controlling terminal and be affected by signals from the keyboard.

daemon(3) is deprecated on macOS as of this writing.

RETURN VALUES

0 on success, -1 on failure

EXAMPLES

xt_daemonize(0, 0);
