30 The zzip_disk_entry_to_data function augments the other
31 zzip_disk_entry_* helpers: here we move a disk_entry pointer (as
32 returned by _find* functions) into a pointer to the data block right
33 after the file_header. Only disk->buffer would be needed to perform the
34 seek but we check the mmapped range end as well.
35
36 The zzip_disk_entry_to_data function returns a pointer into
37 disk->buffer or 0 on error (errno).
38
39 The zzip_disk_entry_to_file_header function does half the job of
40 zzip_disk_entry_to_data where it can augment with
41 zzip_file_header_to_data helper from format/fetch.h
42
43 The zzip_disk_entry_to_file_header function returns a pointer into
44 disk->buffer or 0 on error (errno).
45
46 The zzip_disk_entry_strdup_name function is a big helper despite its
47 little name: in a zip file the encoded filenames are usually NOT zero-
48 terminated but for common usage with libc we need it that way.
49 Secondly, the filename SHOULD be present in the zip central directory
50 but if not then we fallback to the filename given in the file_header of
51 each compressed data portion.
52
53 The zzip_disk_entry_strdup_name function returns a new string buffer,
54 or null on error. If no name can be found then an empty string is
55 returned.
56
57 The zzip_disk_entry_strdup_comment function is similar creating a
58 reference to a zero terminated string but it can only exist in the zip
59 central directory entry.
60
61 The zzip_disk_entry_strdup_comment function returns a new string
62 buffer, or null on error (errno). If no name can be found then an empty
63 string is returned.
