This dirctory contains a set of Visual Studio 2008 build projects for the
current simh code base. When used (with Visual Studio Express 2008 or
Visual Studio Express 2010) it populates a directory tree under the BIN
directory of the Simh distribution for temporary build files and produces
resulting executables in the BIN/NT/Win32-Debug or BIN/NT/Win32-Release
directories (depending on whether you target a Debug or Release build).
The Visual Studio Projects expect that a winpcap developer pack and the
Posix threads for windows package are available in a directory parallel
to the simh directory.
For Example, the directory structure should look like:
.../simh/simhv38-2-rc1/VAX/vax_cpu.c
.../simh/simhv38-2-rc1/scp.c
.../simh/simhv38-2-rc1/Visual Studio Projects/simh.sln
.../simh/simhv38-2-rc1/Visual Studio Projects/VAX.vcproj
.../simh/simhv38-2-rc1/BIN/Nt/Win32-Release/vax.exe
.../simh/windows-build/pthreads/pthread.h
.../simh/windows-build/winpcap/WpdPack/Include/pcap.h

Network devices are capable of using pthreads to enhance their performance.
To realize these benefits, you must build the desire simulator with
USE_READER_THREAD defined. The relevant simulators which have network
support are VAX, VAX780 and PDP11.
Additionally, simulators which contain devices which use the asynchronous
APIs in sim_disk.c and sim_tape.c can also achieve greater performance by
leveraging pthreads to perform blocking I/O in separate threads. Currently
the simulators which have such devices are VAX, VAX780 and PDP11. To
achieve these benefits the simulators must be built with SIM_ASYNCH_IO
defined.
The project files in this directory build these simulators with support for
both network and asynchronous I/O.
