windows socketpair tmpfile: use random prefix fixes #1058 GetTempFileNameA() takes an optional prefix, and a "unique" long value which can optionally be zero, which causes it to automatically increment until a not-yet-existing filename is found. When libevent creates many AF_UNIX socketpairs on windows, it slows down dramatically, due to always using the same blank prefix, and GetTempFileNameA() needing to iterate through all the existing socketpair filenames. With a present and varying prefix, it will have much less need to iterate. It was also possible for a race with other processes also using blank-prefix tmpfile names to result in both trying to start using the same name at the same time (because libevent deletes the file and then re-creates it as a unix socket), which should now be much less likely. Unfortuantely, "much" is just a factor of 32k, because the prefix is only 3 characters, and windows filesystems are case-insensitive, so doing better would require more sophisticated windows API usage and charset trickyness.

Autoconf
$ ./configure $ make $ make verify # (optional) $ sudo make installSee Documentation/Building#Autoconf for more information
CMake (Windows)
Install CMake: https://www.cmake.org
$ md build && cd build $ cmake -G "Visual Studio 10" .. # Or use any generator you want to use. Run cmake --help for a list $ cmake --build . --config Release # Or "start libevent.sln" and build with menu in Visual Studio.See Documentation/Building#Building on Windows for more information
CMake (Unix)
$ mkdir build && cd build $ cmake .. # Default to Unix Makefiles. $ make $ make verify # (optional)See Documentation/Building#Building on Unix (With CMake) for more information
Package Managers
You can download and install libevent using the vcpkg dependency manager:
git clone https://github.com/Microsoft/vcpkg.git cd vcpkg ./bootstrap-vcpkg.sh ./vcpkg integrate install ./vcpkg install libeventThe libevent port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please create an issue or pull request on the vcpkg repository.
2. USEFUL LINKS:
For the latest released version of Libevent, see the official website at http://libevent.org/ .
There’s a pretty good work-in-progress manual up at http://www.wangafu.net/~nickm/libevent-book/ .
For the latest development versions of Libevent, access our Git repository via
$ git clone https://github.com/libevent/libevent.gitYou can browse the git repository online at:
