> The Pepper plug-in API (PPAPI), called Pepper for convenience, is an open-source, cross-platform C/C++ API for web browser plug-ins. Pepper allows a C/C++ module to communicate with the hosting browser and to access system-level functions in a safe and portable way. One of the security constraints in Native Client is that modules cannot make OS-level calls. Pepper provides analogous APIs that modules can use instead.
