@version 1.3.001
|
|
|
|
Header file for POSH, the Portable Open Source Harness project.
|
|
|
|
NOTE: Unlike most header files, this one is designed to be included
|
|
multiple times, which is why it does not have the @#ifndef/@#define
|
|
preamble.
|
|
|
|
POSH relies on environment specified preprocessor symbols in order
|
|
to infer as much as possible about the target OS/architecture and
|
|
the host compiler capabilities.
|
|
|
|
NOTE: POSH is simple and focused. It attempts to provide basic
|
|
functionality and information, but it does NOT attempt to emulate
|
|
missing functionality. I am also not willing to make POSH dirty
|
|
and hackish to support truly ancient and/or outmoded and/or bizarre
|
|
technologies such as non-ANSI compilers, systems with non-IEEE
|
|
floating point formats, segmented 16-bit operating systems, etc.
|
|
|
|
Please refer to the accompanying HTML documentation or visit
|
|
http://www.poshlib.org for more information on how to use POSH.

REVISION:
|
|
|
|
I've been lax about revision histories, so this starts at, um, 1.3.001.
|
|
Sorry for any inconveniences.
|
|
|
|
1.3.001 - 2/23/2006 - Incorporated fix for bug reported by Bill Cary,
|
|
where I was not detecting Visual Studio
|
|
compilation on x86-64 systems. Added check for
|
|
_M_X64 which should fix that.
