NAME
FLintro - Introduction to libfl.a (file IO section)
DESCRIPTION
The functions in this library could be divided in three categories:
- Standard IO functions (open, read, write, etc...)
- Structured IO functions
- Toolbox functions
1. Standard IO
FLIB's low-level IO functions are meant to abstract files such
that an application doesn't need to worry about the underlying
physical storage (disk file that might be memory-mapped,
socket, piped stream, etc...).
The filename passed to the FLopen function may refer to more than
a simple disk file. For example, "mmap:file" or "pipe:cat file"
are valid filename strings. See FLopen for more details.
Once a file is opened, FLread and/or FLwrite can be used to access
its content. These functions provide a simple, uniform way of accessing
file content, but also remove some limitations due to the way the
file was opened. For example, writing in a pipe that was opened for
reading (by using "pipe:cat file") is possible.
Additionally, it is possible to use these low-level IO functions
to replace the stdio.h file functions: open, fopen, read, fread,
write, fwrite, etc...
Functions for managing path names are also provided.
2. Structured IO
Structured files managed by libfl are organized in blocks defined
by an id and a block size, both 4 bytes long. The structure
is based on the original IFF (Interchange File Format) files that
were used on PCs, Macs, SGIs, etc... plus some extensions.
The IDs are divided in two types: those that define the structure
of the file, and those that contain data. The first category contains
4 identifiers:
FORM <size> <type>: marks the start of a group of data blocks,
similar to structures in the C language.
CAT <size> <type>: defines an unsorted group of FORM. For example,
this is used to store images or sounds.
LIST <size> <type>: defines a sorted group of FORM.
(eg: a sequence of images)
PROP <size> <type>: marks the start of a group of data blocks
containing properties shared between FORMs
that are part of a LIST. These properties
can be locally redefined in a way analoguous
to local variables in the C language.
For example, a PROP could be used to define
the dimensions and number of planes of
sequence of image.
Data blocks are defined by:
<id> <size> [data]
Example: a single image could have the following structure:
FORM 12304 IMAG
IHDR 200 ... Header of the image, dimension, number of planes, etc...
LINE 800 ... data of scanline 1 ...
LINE 800 ... data of scanline 2 ...
...
For a library (bunch of images in no specific order):
CAT 64200 IMAG
FORM 12304 IMAG
IHDR 200
...
FORM 12304 IMAG
...
And for a sequence of images (movie):
LIST 64200 IMAG
PROP 208 IMAG
IHDR 200 ... Common header ...
FORM 12394 IMAG
...
FORM 12304 IMAG
IHDR 200 ... Local re-definition ...
...
In the FLIB documentation, the blocks of structure are commonly
called "groups", the blocks of data are named "chunks".
I/O on chunks are done through the FLget/FLput functions and
their variants. The opening/closing of groups is done through
another set of functions: FLbgnrgroup, FLendrgroup, etc...
Note on the structure:
Everything is always written in Big-Endian format (where
the most important byte is always written first). This is the
native format of the SGI MIPS, Motorola and PowerPC/Mac
architectures. In contrast, the Intel/AMD architecture is
little-endian. This library always byte-swaps data to big-endian
automatically, except for IDs, which are normally specified as
a chain of 4 characters and therefore encoded in big-endian format
at compile-time.
A parser can take advantage of the size information that is included
at the beginning of a block to skip the data content if it desires.
Groups and data blocks are always 2-bytes aligned. If a data block
doesn't end at a two-bytes alignment, a padding byte is added to
the end but is not counted in the size of the block following the id.
Additional IDs are defined for groups aligned to 4 or 8 bytes:
FOR4, FOR8, CAT4, CAT8, LIS4, LIS8.
Data blocks inherit the alignment of their parent group. Therefore
creating a block aligned on 2 bytes inside another group aligned on
4 bytes would be illegal. The inverse (a 4-bytes aligned block
inside a 2-bytes aligned block) is perfectly valid.
3. Toolbox
FLIB also provides tools to manage linked lists (FLxxxnode and
FLxxxlist), buffers (FLmalloc and others) and external filters
(FLfilter and FLexec).
Error Management
The I/O functions attempt to prevent underflow/overflow and
end-of-file errors. Still, it is highly recommended that the
calling application do not attempt to continue reading/writing
when an error occur.
For more details on the functions contained inside libfl,
refer to the man pages [claforte: don't know where they are...]
and examples provided with the library.

**
** PATH defines the search path for includes.
** INCL is an include block.

** GEND is the end-of-group marker.
**
** Syntax : PATH # <directory names>
** INCL # <file names>
** EOVC szUnknown
** GEND 0
**
** PATH and INCL are data chuncks and thus inherite alignment.
**
** EOVC and GEND are use in fifo files since the chunk and group sizes
** can not be random accessed. Creating groups or chunks with
** unspecified size on a fifo will give something like :
**
** FORM sz_Fifo TYPE ; start of form
** BLCK sz_Fifo data ; block 1
** EOVC sz_Unknown ; end of block 1
** .... ;
** BLCK sz_Fifo data ; block 2
** EOVC sz_Unknown ; end of block 2
** GEND 0 ; no more block in this FORM
**
** EOVC is a block/group end marker, while GEND is understood as a
** request to close the current group, going up one level.
**
** Using unknown sizes when writing a seekable file will produce a very
** similar structure exept that no EOVC is written. This is very useful
** when parsing a file under construction since the end of group can be
** detected w/o any random access to the group header. The size field of
** GEND is set to zero to allow other standard IFF parsers to skip it
** silently. The EOVC's size field value will produce an error if read
** by a standard parser (w/o fifo extensions).
**
** Warning: for compatibility with the previous version of the IFF parser
** GEND is still followed by sz_Unknown (and EOVC sz_Unknown
** if the file is a fifo).
**
** since there is no reliable way of skipping a block of unknown length
** it is STRONGLY RECOMMENDED that writer and reader of a fifo agree on
** the file's content.
**
** note that the implemented parser is smart enough to locate EOVCs
** in a file, but the skipping process is slow due to intensive read
** and compares. and again, this can NOT be considered 100% reliable.
