Wrapper class for dlopen() and related.
Constructor: Load the specified plugin library from the standard UI plugin directory (/usr/lib/yui/).
|
virtual |
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.
bool YUIPlugin::error | ( | ) | const |
Returns 'true' if there was an error loading the plugin.
string YUIPlugin::errorMsg | ( | ) | const |
Returns a human readable (but in most cases untranslated) error message if there was an error.
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.
|
inlineprotected |
Returns the base name of the plugin library.
|
protected |
Returns the full path of the plugin library.
|
inlineprotected |
Returns the dlopen() handle of the plugin library.
bool YUIPlugin::success | ( | ) | const |
Returns 'true' if there was no error loading the plugin.
void YUIPlugin::unload | ( | ) |
Unload this plugin. 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.
