... if this is not desired, the plugin can instruct the browser not to unload the dll and not to call np_shutdown when the page is left.
...by default, the dll will be unloaded from memory preceded by an np_shutdown call.

... if you want to implement your plugin in c++ or objective-c++, you need to tell the compiler to export them in c format by using extern "c" in the header, like this: #pragma gcc visibility push(default) extern "c" { nperror np_initialize(npnetscapefuncs *browserfuncs); nperror np_getentrypoints(nppluginfuncs *pluginfuncs); void np_shutdown(void); } #pragma gcc visibility pop you can check to be sure your symbols are visible and in standard c format by using the nm utility provided among the mac os x developer tools: [user@foo mymac] nm basicplugin ...
