LibUCW Basics
|
||
|
|
=============
|
||
|
|
|
||
|
|
Every program using LibUCW should start with `#include <ucw/lib.h>` which
|
||
|
|
brings in the most frequently used library functions, macros and types.
|
||
|
|
This should be done before you include any of the system headers, since
|
||
|
|
`lib.h` defines the feature macros of the system C library.
|
||
|
|
|
||
|
|
Portability
|
||
|
|
-----------
|
||
|
|
|
||
|
|
LibUCW is written in C99 with a couple of GNU extensions mixed in where needed.
|
||
|
|
It currently requires the GNU C compiler version 4.0 or newer, but most modules
|
||
|
|
should be very easy to adapt to a different C99 compiler. (A notable exception
|
||
|
|
is `stkstring.h`, which is heavily tied to GNU extensions.)
|
||
|
|
|
||
|
|
The library has been developed on Linux with the GNU libc and it is known to run
|
||
|
|
on Darwin, too. The authors did not try using it on other systems, but most of
|
||
|
|
the code is written for a generic POSIX system, so porting to any UNIX-like system
|
||
|
|
should be a piece of cake.
|
||
|
|
|
||
|
|
Threads
|
||
|
|
-------
|
||
|
|
Generally, functions in the UCW library are reentrant as long as you call them
|
||
|
|
on different data. Accessing the same object from different threads is not supported,
|
||
|
|
unless otherwise told. This also applies to functions acting on any kind of global state.
|
||
|
|
|
||
|
|
ucw/lib.h
|
||
|
|
---------
|
||
|
|
|
||
|
|
!!ucw/lib.h
|
||
|
|
|
||
|
|
ucw/config.h
|
||
|
|
------------
|
||
|
|
This header contains the standard set of types used by LibUCW. It is automatically
|
||
|
|
included by `ucw/lib.h`.
