OnPosix library (also called minimal posix C++ library), is a miniature library to abstract Posix mechanisms to C++ developers. It offers various features like logging, threading, IPC, networking, etc.
Majority of the attributes provided by this library can be found either in a standard library complaint with the C++11 standard or inside the Boost library.
Regrettably, however, for some embedded Linux devices, these libraries cannot display feasible solutions, due to scarcity of memory space (for the Boost libraries) and the lack of new C++ compiler (e.g., on Xilinx MicroBlaze).
On these platforms, the OnPosix library symbolize a nominal and good solution to have object-oriented POSIX mechanisms.
The library is available both as a static (.a) library and a shared (.so) library.
Licensing Information -
The library has been refined in the context of the ERA project, financially supported by the European commission under the FP& program.

-> OnPosix library also offer Observer designer pattern on descriptors (i.e., onposix::DescriptorsMonitor), buffers (i.e., onposix::Buffer) and shared queues (i.e., onposix::PosixSharedQueue and onposix::PosixPrioritySharedQueue).
