NSCPR Control Block Content
NSCPR DSECT
Hex Dec Type/Val Lng Label (dup) Comments ---- ---- --------- ---- -------------- -------- 0000 0 Structure NSCPR HCPNSCPR parameter list mapping THESE FIELDS ARE USED FOR ENTRY TO HCPNSCSG AND HCPNSCSY. - FIRST TIME SEARCH ONLY REQUIRES THAT NSCNAME BE FILLED IN. - SECOND TIME SEARCH OR A RE-SCAN WOULD REQUIRE NSCSNTBK TO BE FILLED IN FOR NSS, DCSS, SEGMENT SPACE, AND MEMBERS. FOR MEMBER SEGMENTS NSCLSNT@ AND NSCLNAME NEED TO FILLED IN TO DETERMINE IF THE MEMBER IS STILL PART OF THE SEGMENT SPACE. NOTES : NSCSNTBK IS FILLED IN BY BOTH ENTRY POINTS. NSCLSNT@ AND NSCLNAME ARE FILLED IN BY HCPNSCSG ONLY. THE INPUT FOR NSCSNTBK, NSCLSNT@, AND NSCLNAME ARE FILLED IN BY HCPNSC MODULE AND SHOULD NOT BE FILLED IN BY THE CALLER. 0000 0 Character 8 NSCNAME INPUT - NAME USED TO LOCATE THE SNTBK ADDRESS. 0008 8 Signed 4 NSCSNTBK OUTPUT - ADDRESS OF THE SNTBK. INPUT - IF ZERO START FROM BEGINNING OF QUEUE. IF NOT ZERO START AT THE SNTBK POINTED TO BY THIS FIELD. 000C 12 Signed 4 NSCLSNT@ OUTPUT - LOGICAL SNTBK ADDRESS WHEN NSCNAME IS A MEMBER DCSS. INPUT - IF NOT ZERO THEN START AT THIS SNTBK ADDRESS TO CONTINUE SEARCHING FOR OTHER DCSS. 0010 16 Character 8 NSCLNAME OUTPUT - THE NAME OF THE LOGICAL SNTBK THAT CONTAINS THE MEMBER NAME. INPUT - A FURTHER CHECK TO ENSURE THAT THE SNTBK IS STILL VALID TO CONTINUE SEARCHING. 00000018 NSCBSIZE *-NSCPR BYTE SIZE OF THIS DSECT. 00000003 NSCSIZE (NSCBSIZE+7)/8 SIZE IN DOUBLEWORDS.
