Between Unix and Windows socket are quite different: - on Windows sockets have a different namespace from C file descriptors so you can't use read/write/close or similar functions; - errors are not stored in errno but you must be read/write the errors with specific function; - sometimes sockets are put in non-blocking mode automatically calling some functions; - SOCKET type is 64 bit on Windows 64 which does not fit technically in an int. Is however safe to assume them to fit in an int. So encapsulate the socket APIs in some definition to make easier and more safe to deal with them. Where the portability to Windows would make to code more offuscated a Unix style was preferred. For instance if errors are detected errno is set from Windows socket error instead of changing all code handling. Fortunately on Windows Qemu core interface accepts socket (but not other types like C file descriptors!).

SPICE: Simple Protocol for Independent Computing Environments
=============================================================
SPICE is a remote display system built for virtual environments which
allows you to view a computing 'desktop' environment not only on the
machine where it is running, but from anywhere on the Internet and
from a wide variety of machine architectures.
Installation
------------
The SPICE package uses GNU autotools, so the build install process
follows the standard process documented in the INSTALL file. As a
quick start you can do
./configure --prefix=/usr --sysconfdir=/etc \
--localstatedir=/var --libdir=/usr/lib
make
sudo make install
Or to install into a private user specific location
./configure --prefix=$HOME/spice
make
make install
The following mandatory dependencies are required in order to
build SPICE
Spice protocol >= 0.14.0
Pixman >= 0.17.7
OpenSSL
libjpeg
zlib
The following optional dependencies increase the available
functionality
Cyrus-SASL
libcacard >= 2.5.1 (Smartcard support)
Opus >= 1.0.0 (Opus audio encoding support)
LZ4 (LZ4 compression support)
GStreamer >= 1.0.0
Communication
-------------
To communicate with the development team, or to post patches
there is a technical mailing list:
http://lists.freedesktop.org/mailman/listinfo/spice-devel
There is also a mailing list for new release announcements:
http://lists.freedesktop.org/archives/spice-announce/
To view known bugs, or report new bugs, in SPICE visit
https://gitlab.freedesktop.org/spice/spice/issues/new?
Bugs found when using an OS distribution's binary packages should
be reported to the OS vendors' own bug tracker first.
The latest SPICE code can be found in GIT at:
https://gitlab.freedesktop.org/spice/
