Describes the generic node descriptor layout. This object represents the ND obtained from the CHSC instruction: /* ND Flags */ int bValidity :3; /* 1:is ND valid */ int bNodeType :1; /* 1:0=dev,1=chnlsubstm nod*/ int bInternal :1; /* internal(1)/external(0) */ int bCHPinvalid :1; /* IF =1,NDCHPID is invalid*/ int bNDRsvd1 :2; /* spare bits for alignment*/ char NDRsvd1; /* reserved by architecture*/ char NDClass; /* Class for subsystem node*/ char NDCHPID; /* CHP ID for specified int*/ 6]; /* type number of the SDC */ char NDModelNum[3]; /* ND model number in the form of 3 EBCDIC OCTETS */ char NDMfgr[3]; /* ND manufacturer in the form of 3 EBCDIC OCTETS */ char NDMfgrPlant[2]; /* ND plant of manufacture (2 EBCDIC OCTETS) */ char NDSeqNum[12]; /* ND sequence number (12 EBCDIC OCTETS) */ char NDTag[2]; /* ND tag */
