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