Write-delete record types
There are four sections in the journal records written for write-delete record types:
v The FLJB_GENERAL_DATA section,
v The FLJB_WRITE_DELETE_DATA section, and
v The two caller data image sections, which consist of:
– FLJB_WDD_BASE_KEY (the length of which is given by
FLJB_WDD_BASE_KEY_LENGTH in FLJB_WRITE_DELETE_DATA)
– FLJB_WDD_PATH_KEY (the length of which is given by
FLJB_WDD_PATH_KEY_LENGTH in FLJB_WRITE_DELETE_DATA).
These sections contain the image of the caller data as the base key, and, if the
data set is a path, the path.
The format of such a record written for write-delete record types is shown in
Figure 81.
FLJB_GENERAL_DATA
12-byte general data section.
FLJB_WRITE_DELETE_DATA
12-byte write-delete data section.
FLJB_WDD_BASE_KEY
Variable-length base key.
FLJB_WDD_PATH_KEY

See Figure 79 on page 719 for the format of the FLJB_GENERAL_DATA section.
The format of the FLJB_WRITE_DELETE_DATA section is shown in Figure 82 on
page 722.
