I have done some research to this effect but it is unclear if this is possible to use libuv on IOS/Android? If its not possible what is restricting it? I am looking to write a C++ library that I can use for the same application on IOS, Android, Windows, OSX and Linux. Libuv seems to come close to fitting all of the requirements for sockets and threads.

Actually <code>libuv</code> hasn't a build target for iOS, but you always can add it's source files to your <code>xcode</code> project and build. I have build it this way and it works fine for me.

Can libuv(node.js's async lib) run on Apple IOS / Android?
