Member Function Documentation

void dsDaemon::addChild (  pid_t    npid )  [protected, inherited]

pid_t dsDaemon::fork_child (    )  [virtual, inherited]

fork child. Default function increase child counter and then fork. It's better to call return dsDaemon::fork_child() at the end of overloaded function. if overloaded function returns -1 (fork error) child will not be intialised. Reimplemented in dsHttpDaemon.

int dsDaemon::init_globals (    )  [virtual, inherited]

Perform tasks after daemon detach, but before first fork all file handlers is closed to this point. Reimplemented in dsHttpDaemon.

void dsDaemon::kill_running (    )  [inherited]

read pid file and kill running instance

void dsDaemon::processPidFile (    )  [protected, inherited]

int dsDaemon::reinit (    )  [virtual, inherited]

Function to call from SIGHUP handler. Week point use it with care.

void dsDaemon::removeChild (  pid_t    npid )  [protected, inherited]

void dsDaemon::shutdown_child (    )  [virtual, inherited]

This function called when child terminated wether by SIGTERM or normally Reimplemented in dsHttpDaemon.

int dsDaemon::waitForFreeSlot (  pid_t    pid )  [protected, inherited]

Waits for free slot in child array, and returns number of found slot

Friends And Related Function Documentation

int DaemonFlags (  char *    str )  [friend, inherited]

Convert text reperesentation of daemon file into binary flags

void daemonize (  dsDaemon *    sd, int    options = 0 )  [friend, inherited]

Perform basic system tasks to become a daemon: close all handlers, allocate new process group and detach sd pointer to dsDaemon object options daemon flags

void dsSafeSleep (  int    secs, int    nsecs = 0 )  [friend, inherited]

safe sleep: implement sleep by nanosleep or select timer (TODO), instead of using SIGALARM or sleep() to avoid possible interference with user application

void SIGANY_hdl (  int    sig )  [friend, inherited]

void SIGCHLD_hdl (  int    sig )  [friend, inherited]

void SIGINT_hdl (  int    sig )  [friend, inherited]
