Posh is a software framework
used in cross-platform
software development
. It was created by Brian Hook. It's BSD licensed and currently at version 1.3.002.
The Posh software framework provides a header file
and an optional C
source file.
Posh does not provide alternatives where a host platform
does not offer a feature, but informs through preprocessor
macros what's supported and what not. It sets macros to assist in compiling with various compiler
s (such as GCC
, MSVC
and OpenWatcom
), and different host endianness
es. In its simplest form, only a single header file is required. In the optional C source file, there are functions
for byte swapping and in-memory serialisation/deserialisation
.
Brian Hook also created SAL (Simple Audio Library) that utilises Posh. Both are featured in his book "Write Portable Code". Posh is also used in Ferret
and Vega Strike
.
