Function Documentation

finish_daemon()

int finish_daemon

(

const char *

desired_cwd

)

Finish putting the process into daemon mode: drop standard fds, and tell the parent process to exit. (Note: it's safe to call this more than once: calls after the first are ignored. Calls start_daemon first if it hasn't been called already.) Return true if we actually did a fork; false if we didn't.

Definition at line 121 of file daemon.c.

start_daemon()

int start_daemon

(

void

)

Start putting the process into daemon mode: fork and drop all resources except standard fds. The parent process never returns, but stays around until finish_daemon is called. (Note: it's safe to call this more than once: calls after the first are ignored.) Return true if we actually forked and this is the child; false otherwise.

start_daemon_has_been_called()

bool start_daemon_has_been_called
