Function Documentation

void di_log (  di_log_level_flags  log_level, const char *  format,   ... )

Logs the resolved formatstring with log_level Parameters: log_level  the level of the message format  printf compatible format

unsigned int di_log_set_handler (  di_log_level_flags  log_levels, di_log_handler *  log_func, void *  user_data )

Sets a log handler Parameters: log_levels  levels log_func  the log handler user_data  data for log_func { static unsigned int handler_id = 0; di_log_handler_struct *handler; handler = di_new (di_log_handler_struct, 1); handler->id = ++handler_id; handler->log_level = log_levels; handler->log_func = log_func; handler->user_data = user_data; di_slist_append (&handlers, handler); return handler_id; }

void di_vlog (  di_log_level_flags  log_level, const char *  format, va_list  args )

Logs the resolved formatstring with log_level Parameters: log_level  the level of the message format  printf compatible format args  variable arguments list { char buf[1024]; int fatal = log_level & DI_LOG_FATAL_MASK; di_log_handler *log_func; void *user_data; vsnprintf (buf, sizeof (buf), format, args); log_func = internal_di_log_get_handler (log_level, &user_data); log_func (log_level, buf, user_data); if (fatal) exit (1); }
