C++ (Cpp) init_device_info Examples

Example #1

File: monitor.c Project: erik/cudamon

struct monitor* monitor_new(void)
{
  struct monitor* mon = calloc(1, sizeof(struct monitor));

  // Half a second is a decent default
  mon->update_interval = 500;

  mon->active = 1;

  // Fetch the basic info that should hold true throughout execution
  init_device_info(mon);

  return mon;
}
