sqfs_u16 size
The size of the entry name.
Definition: dir.h:98
sqfs_u8 name[]
Name of the name of the first entry after the header.
Definition: dir.h:139
sqfs_u32 start_block
The location of the meta data block containing the inodes for the entries that follow, relative to the start of the inode table.
