Hi, In the "Guidelines and rules for plugins" is this statement: "Obviously [plugins] must not access memory locations that other threads could modify [while the mutex lock is not taken], so they should only access local variables, not class variables (which includes the parameter library)". I think it should be OK to access member variables of the plugin class (i.e. the class derived from NDPluginDriver), in addition to local (stack) variables. And I presume that by "class variables" what's meant is members that are generally referred to in C++ as static member variables. Am I correct? Cheers, Phil --
