Projects / ucommon


UCommon is a lightweight C++ library to facilitate using C++ design patterns even for very deeply embedded applications, such as for systems using uClibc along with POSIX threading support. For this reason, UCommon disables language features that consume memory or introduce runtime overhead. UCommon introduces some design patterns from Objective-C, such as reference counted objects, memory pools, and smart pointers. UCommon introduces some new concepts for handling of thread locking and synchronization.
