 NAME       : HCPXDIBK
 DESCRIPTION: XDISK services messaging content
 DSECT      : XDIBK
 FUNCTION   : Maps data passed between systems for all XDISK services
 LOCATED BY : MBHBFPTL
 CREATED BY : HCPKCDCB
 DELETED BY : HCPKCDDB
 REFERENCES : None
 SERIALIZED : Input to HCPKCDCB is the length in bytes of the data area being
              requested.  This is the size of the XDIBK we need for a particular
              request.  This data buffer is used by the system making the
              request of replying with HCPSOCK.  HCPKCDDB should not be called
              to release the storage associated with the data buffer (XDIBK)
              until the HCPSOCK call has returned control.
 COMPATIBILITY AND MIGRATION CONCERNS : None
 RELOCATION CONSIDERATIONS : None
 COMMENTS   : The XDIBK is variable in size and maps all requests and replies
              made by XDISK services.
