$SET_DEVICE

   Modifies the characteristics of a device or the paths used to
   access that device.

   For synchronous completion, use the Set Device Characteristics
   and Wait ($SET_DEVICEW) service. The $SET_DEVICEW service is
   identical to the $SET_DEVICE service, except that $SET_DEVICEW
   returns to the caller only after the requested action has taken
   effect.

   For additional information about system service completion, see
   the Synchronize ($SYNCH) service.

   Format

     SYS$SET_DEVICE  [efn] [,chan] [,devnam] ,itmlst [,iosb]

                     [,astadr] [,astprm] [,nullarg]

   C Prototype

     int sys$set_device  (unsigned int efn, unsigned short int chan,

                         void *devnam, void *itmlst, struct _iosb

                         *iosb, void (*astadr)(__unknown_params),

                         int astprm, struct_generic_64 *nullarg);
