Function Documentation

void assertion_init (  void   )  [static]

time_t check_cpu_usage (  void   )  [static]

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

void close_fds (  gint  fd  )  [static]

Closes all file descriptors greater or equal to ``fd''.

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 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 )

gboolean main_timer (  gpointer  p  )  [static]

Main timer routine, called once per second.

RCSID (  "$Id:main.  c, v 1.264 2005/11/29 22:14:55 rmanfredi Exp $"  )

gboolean scan_files_once (  gpointer  p  )  [static]

Scan files when the GUI is up.

void search_gui_store_searches (  void   )

Persist searches to disk.
