Files


  • A process gains access to a file handle when a thread uses DosOpen (etc.) or because it inherited the handle (e.g. stdin).
  • Handles can refer to objects mediated by an IFS (files, dirs), a volume (e.g. A:), a named or unnamed pipe, or a device (e.g. con$).
  • A handle is an index into a process' JFN tab.
