5 | * An object can be an RTEMS object (chain based stuff) or |

6 | * a "misc" object such as a device driver. |
---|
7 | * |
---|
8 | * Each object has its own file in this directory (eg: extension.c) |

9 | * That file provides routines to convert a "native" structure |

10 | * to its canonical form, print a canonical structure, etc. |

11 | * |

12 | * TODO: |
---|
13 | * should allow for non-numeric id's??? |
