NAME : HCPMIHDR DESCRIPTION: MISSING INTERRUPT HANDLER HEADER BLOCK DSECT : MIHDR FUNCTION : THE MIHDR CONTAINS THE GENERAL INFORMATION THAT PERTAINS TO THE HANDLING OF MISSING INTERRUPT CONDITIONS. IN ADDITION, IT ACTS AS THE ANCHOR FOR THE CHAIN OF HCPMIOBJS. LOCATED BY : IORMIPTR FIELD OF IORBK - BLOCKS USED FOR HANDLING MISSING INTERRUPT CONDITIONS CREATED BY : MIHDR'S ARE DYNAMICALLY CREATED BY HCPMHLAT. DELETED BY : MIHDR'S ARE DELETED BY HCPMHLDT WHEN THERE ARE NO MORE MIOBJ'S ASSOCIATED WITH THE MIHDR.
