NAME : HCPHCIBK DESCRIPTION: Hardware Console Integration Message Buffer DSECT : HCIBK FUNCTION : HCPHCIBK maps the message buffers used to control the hardware console information to be displayed on the guest system console (guest's logon terminal). LOCATED BY : Several queues anchored within the SVPBK contain HCIBK message buffer blocks: SVPWBUF field of SVPBK SVPRBUF field of SVPBK SVPPBUF field of SVPBK CREATED BY : HCPPCXIN, HCPPCW76 DELETED BY : HCPPCW77, HCPPCXDL, HCPPCXRS SERIALIZED : None
