Detailed Description

a UInput object fires callbacks when a file or a socket gets data.

Example:

    int source = ...;
    uptr<UInput> i = new UInput(source);
    i->onAction( ucall(x, y, printArgs) );
    i->onAction( ucall(obj, val, &Demo::doIt) );
 

• callbacks printArgs(x, y) and obj->doIt(val) are fired when the source receives data
