You shouldn't have PPAPI_PROXY_EXPORT here.

That adds __attribute__((visibility("default"))), which is something we don't
really want on Linux (it would override "-fvisibility=hidden" which most Chrome
code is compiled with), and I think it won't affect code linked into the NaCl
IRT.

Oh, was PPAPI_PROXY_EXPORT just needed to make the components build work?  In
which case, it's OK as it is.

[hidehiko, 2014/02/20 18:50:01]

Exactly. Without this component build would be failed.

+extern "C" {
+#endif

+// The entry point for the main thread of the PPAPI plugin process.
+PPAPI_PROXY_EXPORT int PpapiPluginMain(void);
+
+PPAPI_PROXY_EXPORT void PpapiPluginRegisterThreadCreator(
+    const struct PP_ThreadFunctions* new_funcs);
+
+// Overwrites the IPC channels for the browser and the renderer by the given

[Mark Seaborn, 2014/02/19 17:00:30]

"Overwrites" -> "Sets"?

[hidehiko, 2014/02/20 18:50:01]

Done.

+// FD #s. This will be used for non-SFI mode. Must be called before

[Mark Seaborn, 2014/02/19 17:00:30]

Nit: '#s' -> 'numbers'.  This will be read more than it is written. :-)

[hidehiko, 2014/02/20 18:50:01]

Done :-)
