Getting started using the C API

You must implement the following three functions:

• PPP_InitializeModule which is called on startup and returns 0 on success.
• PPP_ShutdownModule which is called on shutdown.
• PPP_GetInterface which is called when a new plugin instance is created for a page.

An example "no op" implementation of these three functions in C is in examples/stub/stub.c in the source repository.

You must compile these functions such that the names are exported from the shared library to call. For Microsoft VC and GCC the PP_EXPORT macro used in the declarations should be sufficient.

Getting started using the C++ API

Using the C++ wrapper, there is slightly more to the stub program, but it does more. You must implement these things:

• pp::CreateModule which is the factory function for your plugin's specific pp::Module implementation.
• A specialization of pp::Module that implements CreateInstance, which is in turn the factory function for your plugin's specific pp::Instance implementation.
• A specialization of pp::Instance which represents one plugin on a web page.

An example "no op" implementation of these concepts is in examples/stub/stub.cc in the source repository.
