A description of each of the structures, and the sections within them, now follows:
Read-only, read-update, write-update, write-add, write-add
complete record types
There are four sections in the journal records written for read-only, read-update,
write-update, write-add, and write-add complete record types:
v The FLJB_GENERAL_DATA section,
v The FLJB_COMMON_DATA section, and
v The caller data image sections which consist of the FLJB_CD_KEY (the length of
which is given in FLJB_COMMON_DATA) and the FLJB_CD_DATA section. The
FLJB_CD_DATA section (the length of which is given in FLJB_COMMON_DATA)
contains the image of the caller data.
The format of such a record written for these record types is shown in Figure 78.
