Destructor.
Please note that this will NOT attempt to unload the plugin library since this is usually counterproductive. If unloading the plugin is desired, call unload() manually.

void * YUIPlugin::locateSymbol | ( | const char * | symbol | ) |
Try to locate the specified symbol (function or global variable) in the plugin library.
Returns the in-memory address of that symbol or 0 if it could not be found or if loading the plugin library had failed in the constructor.

void YUIPlugin::unload | ( | ) |

This calls dlclose() which will unload the plugin library if it is no longer used, i.e. if the reference count dlopen() uses reaches 0.
