Info

Exec status is the operating system status returned in word 3 or 4 of an I/O request packet (depending on theinterface).Sub-status is the operating system sub-status returned farther down in an I/O request packet (depending onthe interface).Adapter Type is the type of adapter and interface being used to service this connection. The current typesare as follows:0 PB140/NB140/A140 via IOARB1 PB140/NBl40/A140 via IOADH2 A142 via IOADH3 PB22x/NB22x/A22x via IOFEP4 PB22x/NB22x/A22x via IOAID5 PB140/NBl4O via IOAID6 A142 via IOAID7 PB22x/NB22x/A22x via IOAIDChannel Status Words are the actual status words returned by the I/O processor. For the IOFEP (SINCH)interface, these words are not available. For other interfaces the Processor and Storage manual for the processortype should be consulted for the number of channel status words and their formats. The request to obtaindriver statistics is communicated to NETEX by the DSTATUS macro call.Operation ParametersDSTATUS[W] nrb [err-return]DSTATUSWIf specified, control will not return to the caller until the request is completed. Otherwise, return willbe madenrbThis required parameter is the address of the updated NETEX request block (NRB) to be used withthe procedure. This field may have the following form:U-field[,X-reg[,J-desig]]err-returnThis optional parameter is the address for transfer of control if the request completes with an error indicationin NRBSTAT.DSTATUS Entry ParametersThe following NRB fields are used by DSTATUS on entry:NRBNREF The path index returned by DCONNECT.NRBREQSet by the procedure to DSTATUS.NRBBUFLThe maximum number of words of status to accept.NRBBUFA The address of the area where the status data is stored.DSTATUS ResultsThe following NRB fields are updated when DSTATUS completes:NRBSTATRequest status: -1 ‘in progress’; 0 ‘successfully completed’; otherwise a positivenonzero NETEX error code.NRBLENThe length of status received.Page 76 Driver Interface MAN-REF-H307IP-04
