pack_fopen_chunk
pack_fopen_chunk(3alleg4) Allegro manual pack_fopen_chunk(3alleg4)NAME
pack_fopen_chunk - Opens a sub-chunk of a file. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
PACKFILE *pack_fopen_chunk(PACKFILE *f, int pack);
DESCRIPTION
Opens a sub-chunk of a file. Chunks are primarily intended for use by the datafile code, but they may also be useful for your own file rou-
tines. A chunk provides a logical view of part of a file, which can be compressed as an individual entity and will automatically insert and
check length counts to prevent reading past the end of the chunk. The PACKFILE parameter is a previously opened file, and `pack' is a bool-
ean parameter which will turn compression on for the sub-chunk if it is non-zero. Example:
PACKFILE *output = pack_fopen("out.raw", "w!");
...
/* Create a sub-chunk with compression. */
output = pack_fopen_chunk(output, 1);
if (!output)
abort_on_error("Error saving data!");
/* Write some data to the sub-chunk. */
...
/* Close the sub-chunk, recovering parent file. */
output = pack_fclose_chunk(output);
The data written to the chunk will be prefixed with two length counts (32-bit, a.k.a. big-endian). For uncompressed chunks these will both
be set to the size of the data in the chunk. For compressed chunks (created by setting the `pack' flag), the first length will be the raw
size of the chunk, and the second will be the negative size of the uncompressed data.
To read the chunk, use the following code:
PACKFILE *input = pack_fopen("out.raw", "rp");
...
input = pack_fopen_chunk(input, 1);
/* Read data from the sub-chunk and close it. */
...
input = pack_fclose_chunk(input);
This sequence will read the length counts created when the chunk was written, and automatically decompress the contents of the chunk if it
was compressed. The length will also be used to prevent reading past the end of the chunk (Allegro will return EOF if you attempt this),
and to automatically skip past any unread chunk data when you call pack_fclose_chunk().
Chunks can be nested inside each other by making repeated calls to pack_fopen_chunk(). When writing a file, the compression status is
inherited from the parent file, so you only need to set the pack flag if the parent is not compressed but you want to pack the chunk data.
If the parent file is already open in packed mode, setting the pack flag will result in data being compressed twice: once as it is written
to the chunk, and again as the chunk passes it on to the parent file.
RETURN VALUE
Returns a pointer to the sub-chunked PACKFILE, or NULL if there was some error (eg. you are using a custom PACKFILE vtable).
