NAME

       zzip_disk_entry_to_data, zzip_disk_entry_to_file_header, zzip_disk_entry_strdup_name,
       zzip_disk_entry_strdup_comment -  helper functions for (mmapped) zip access api

SYNOPSIS

       #include <zzip/mmapped.h>

       zzip_byte_t *
       zzip_disk_entry_to_data(ZZIP_DISK * disk, struct zzip_disk_entry * entry)

       struct zzip_file_header *
       zzip_disk_entry_to_file_header(ZZIP_DISK * disk, struct zzip_disk_entry *entry)

       zzip__new__ char *
       zzip_disk_entry_strdup_name(ZZIP_DISK * disk, struct zzip_disk_entry *entry)

       zzip__new__ char *
       zzip_disk_entry_strdup_comment(ZZIP_DISK * disk, struct zzip_disk_entry *entry)

DESCRIPTION

        The zzip_disk_entry_to_data function augments the other zzip_disk_entry_* helpers: here
       we move a disk_entry pointer (as returned by _find* functions) into a pointer to the data
       block right after the file_header. Only disk->buffer would be needed to perform the seek
       but we check the mmapped range end as well.

        The zzip_disk_entry_to_data function returns a pointer into disk->buffer or 0 on error
       (errno).

        The zzip_disk_entry_to_file_header function does half the job of zzip_disk_entry_to_data
       where it can augment with zzip_file_header_to_data helper from format/fetch.h

        The zzip_disk_entry_to_file_header function returns a pointer into disk->buffer or 0 on
       error (errno).

        The zzip_disk_entry_strdup_name function is a big helper despite its little name: in a
       zip file the encoded filenames are usually NOT zero-terminated but for common usage with
       libc we need it that way. Secondly, the filename SHOULD be present in the zip central
       directory but if not then we fallback to the filename given in the file_header of each
       compressed data portion.

        The zzip_disk_entry_strdup_name function returns a new string buffer, or null on error.
       If no name can be found then an empty string is returned.

        The zzip_disk_entry_strdup_comment function is similar creating a reference to a zero
       terminated string but it can only exist in the zip central directory entry.

        The zzip_disk_entry_strdup_comment function returns a new string buffer, or null on error
       (errno). If no name can be found then an empty string is returned.
