Synopsis

========

This package provides semi-portable access to hardware provided

atomic memory operations.  These might allow you to write code:

- That does more interesting things in signal handlers.

- Makes more effective use of multiprocessors by allowing you to write

  clever lock-free code.  Note that such code is very difficult to get

  right, and will unavoidably be less portable than lock-based code.  It

  is also not always faster than lock-based code.  But it may occasionally

  be a large performance win.

- To experiment with new and much better thread programming paradigms, etc.

For details and licensing restrictions see the files in the doc

subdirectory.

This is version 7.2alpha7 of libatomic_ops.

Installation and Usage

======================

The configuration and build scripts for this package were generated by

Automake/Autoconf.  "./configure --prefix=; make; make install"

in this directory should work.  For a more customized build, see "INSTALL"

and the output of "./configure --help".

Note that much of the content of this library is in the header files.

However, two small libraries are built and installed:

- libatomic_ops.a is a support library, which is not needed on some platforms.

  This is intended to be usable, under some mild restrictions, in free or

  proprietary code, as are all the header files.  See doc/LICENSING.txt.

- libatomic_ops_gpl.a contains some higher level facilities.  This code is

  currently covered by the GPL.  The contents currently correspond to

  the headers atomic_ops_stack.h and atomic_ops_malloc.h.

Platform Specific Notes

=======================

Win32/64: src/Makefile.msft contains a very simple Makefile for building

and running tests and building the gpl library.  The core atomic_ops

implementation is entirely in header files.

HP-UX/PA-RISC: aCC -Ae won't work as a C compiler, since it doesn't support

inline assembly code.  Use cc.
