-
- I always wanted a library, that would emulate as much as possible of a
- **IX/BSD environment on the Amiga, so that programs (usually programming
- tools) written for **IX/BSD could be ported in a quick and straight forward
- way to the Amiga. I guess the library accomplishes this goal fairly well.
-
- What it is and what it isn't
- ============================
-
- The design of the library was therefore guided towards **IX/BSD
- compatibility, and *not* :
- o to be too conservative with resources
- o to be particularly conformant to Amiga habits. Thus if I had to decide
- whether I should make a function act more like an Amiga function or
- more like a **IX/BSD one, I decided for the latter. As an example:
- _cli_parse() does wildcard expansion, and tries to apply more or less
- **IX/BSD shell semantics to an argument line, it doesn't call
- ReadArgs().
- The types used in my own source code are all from sys/types.h (except
- BPTR). I don't think capitalized identifiers should be used for typedef'd
- types. According to C-conventions, anything written in captials should
- be `#undef'inable, which typedefs aren't. Thus if you write contributions
- to be included into the official distribution of this library, code
- according to this. Use `u_char' and not UBYTE, etc. I don't care that
- this is against the Commodore coding standard, this is my code, and
- I decide what I like and what not.
- o to be particularly suited for inclusion into a shared library, although
- most things *are* shared now. What I'd really want for the Amiga is
- the concept of a dynamic linker.
-
- On the other hand, it should be:
- o expandable. As an example, a file descriptor already can refer to `real'
- files, directories, memory buffers treated as files. I plan to add
- sockets in some next release (Commodore: please get out some examples
- on how to use SANA-II stuff, so my sockets can be compatible!)
- o patchable. If you want some function to behave differently, you can
- SetFunction() it, and the rest of the library should use your new entry.
- NOTE: I used this only for major functions, that may reasonably change.
- I didn't call functions like strcmp(), strlen(), bcopy() that way for
- efficiency reasons (and my lazyness to change the whole string/
- and other libraries;-)))
- This version doesn't particularly follow this goal very well, mostly
- stdio is still the original BSD code, and doesn't use syscall()...
-
- Also included is ixtrace, a utility which lets you scan every call made
- through the library base when you install one of the *.trace versions of
- the library.
