Are oSIP and partysip portable?
oSIP can be built without thread and semaphore support. In this case, you can use oSIP in non-multi threaded applications. In this case, no dependency beyond the standard C library is needed. That say, partysip will require a threaded version of osip. oSIP hides implentations details for partysip: it provides a common interface for posix_thread interface, psos interface, windows interface and vxworks interface. The same is implemented for mutex and semaphore which are mandatory in a threaded architecture.
