PhysicsFS is a library to provide abstract access to various archives.
|
|
It is intended for use in video games, and the design was somewhat
|
|
inspired by Quake 3's file subsystem. The programmer defines a "write
|
|
directory" on the physical filesystem. No file writing done through the
|
|
PhysicsFS API can leave that write directory, for security. For example,
|
|
an embedded scripting language cannot write outside of this path if it
|
|
uses PhysFS for all of its I/O, which means that untrusted scripts can
|
|
run more safely. Symbolic links can be disabled as well, for added
|
|
safety. For file reading, the programmer lists directories and archives
|
|
that form a "search path". Once the search path is defined, it becomes
|
|
a single, transparent hierarchical filesystem. This makes for easy
|
|
access to ZIP files in the same way as you access a file directly on the
|
|
disk, and it makes it easy to ship a new archive that will override a
|
|
previous archive on a per-file basis. Finally, PhysicsFS gives you
|
|
platform-abstracted means to determine if CD-ROMs are available, the
|
|
user's home directory, where in the real filesystem your program is
|
|
running, etc.
