OSProcessPlugin (OSPP) provides access to Unix/Linux, Mac OS X, and Windows operating system functions. OSPP is used by OSProcess for low level system access. Stub classes are provided for other operating systems (help welcome here). OSProcessPlugin contains the complete source code for the Unix and Windows OSProcessPlugin (OSPP). Generate the plugin with VMMaker. No external support code is required. See also XDisplayControlPlugin, which contains the X display support primitives previously included in OSPP, and AioPlugin, which contains the asynchronous I/O event forwarding primitives previously included in OSPP.
