Function Documentation

time_t check_cpu_usage (  void   )  [static]

Check CPU usage. Returns: current (exact) system time.

gboolean debugging (  guint  t  )

Are we debugging anything at a level greater than some threshold "t"?

void gtk_gnutella_atexit (  void   )  [static]

Invoked as an atexit() callback when someone does an exit().

void gtk_gnutella_exit (  gint  n  )

Exit program, return status `n' to parent process. Shutdown systems, so we can track memory leaks, and wait for EXIT_GRACE seconds so that BYE messages can be sent to other nodes.

void gtk_gnutella_request_shutdown (  void   )

void handle_arguments (  int  argc, char **  argv )  [static]

void icon_timer (  void   )

void log_cpu_usage (  tm_t *  since_time, gdouble *  prev_user, gdouble *  prev_sys )  [static]

Log cpu used since last time. Parameters: since_time  time at which the measurement period started, updated prev_user  previous total user time, updated if not NULL prev_sys  previous total system time, updated if not NULL

void log_handler (  const gchar *  domain, GLogLevelFlags  level, const gchar *  message, gpointer  user_data )  [static]

void log_init (  void   )  [static]

int main (  int  argc, char **  argv )

guint32 main_get_build (  void   )

Get build number.

gboolean main_timer (  gpointer  p  )  [static]

Main timer routine, called once per second.

gboolean option_match (  const gchar *  a, const gchar *  b )  [static]

Checks whether two strings qualify as equivalent, the ASCII underscore character and the ASCII hyphen character are considered equivalent. Returns: whether the two strings qualify as equivalent or not.

const gchar* option_pretty_name (  const gchar *  name  )  [static]

Copies the given option name to a static buffer replacing underscores with hyphens. Returns: a pointer to a static buffer holding the pretty version of the option name.

void prehandle_arguments (  char **  argv  )  [static]

gint reopen_log_files (  void   )  [static]

gboolean scan_files_once (  gpointer  p  )  [static]

Scan files when the GUI is up.

void search_gui_store_searches (  void   )

Persist searches to disk.

void sig_alarm (  int  n  )  [static]

Force immediate shutdown of SIGALRM reception.

void sig_chld (  int  n  )  [static]

void sig_hup (  int  n  )  [static]

void sig_terminate (  int  n  )  [static]

void slow_main_timer (  time_t  now  )  [static]

gchar underscore_to_hyphen (  gchar  c  )  [inline, static]

void usage (  int  exit_code  )  [static]
