Field Documentation

count

sqfs_u32 count

Number of consecutive key-value pairs.

Definition at line 109 of file xattr.h.

size

sqfs_u32 size

Total size of the uncompressed key-value pairs in bytes, including data structures used to encode them.

xattr

sqfs_u64 xattr

Location of the first key-value pair.

This is a reference, i.e. the bits 16 to 48 hold an offset that is added to xattr_table_start from sqfs_xattr_id_table_t to get the location of a meta data block that contains the first key-value pair. The lower 16 bits store an offset into the uncompressed meta data block.
