  30. // below registry key:
  31. // "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SmDebug"
  32. // and in it create a value whose name is the component's debugging tag name
  33. // (the "comp" parameter to the DECLARE_INFOLEVEL macro) and whose data is
  34. // the desired infolevel in REG_DWORD format.
  35. // e.g. Sched = REG_DWORD 0x707

  154. // This macro defines xxDebugOut where xx is the component prefix
  155. // to be defined. This declares a static variable 'xxInfoLevel', which
  156. // can be used to control the type of xxDebugOut messages printed to
  157. // the terminal. For example, xxInfoLevel may be set at the debug terminal.
  158. // This will enable the user to turn debugging messages on or off, based
  159. // on the type desired. The predefined types are defined below. Component
  160. // specific values should use the upper 24 bits
  161. //
  162. // To Use:
  163. //
  164. // 1) In your components main include file, include the line
  165. // DECLARE_DEBUG(comp)
  166. // where comp is your component prefix
  167. //
  168. // 2) In one of your components source files, include the line
  169. // DECLARE_INFOLEVEL(comp)
  170. // where comp is your component prefix. This will define the
  171. // global variable that will control output.
  172. //
  173. // It is suggested that any component define bits be combined with
  174. // existing bits. For example, if you had a specific error path that you
  175. // wanted, you might define DEB_<comp>_ERRORxxx as being
  176. //
  177. // (0x100 | DEB_ERROR)
  178. //
  179. // This way, we can turn on DEB_ERROR and get the error, or just 0x100
  180. // and get only your error.
