  7.  *  This header file contains the function prototype for the asofyet  *
  8.  *  undocumented DosQProcStatus API.  It also contains the structure  *
  9.  *  definitions that are used in the buffer that is returned by the   *
  10.  *  API call.                                                         *
  11.  *                                                                    *
  12.  *  In order to invoke DosQProcStatus, your .DEF file must contain    *
  13.  *  this entry:                                                       *
