I don't see anything in the documentation which would indicate this. However, the current implementation seems to be wrong since it always returns the last load error even when called repeatedly. SUSv3 says: "If no dynamic linking errors have occurred since the last invocation of dlerror(), dlerror() shall return NULL. Thus, invoking dlerror() a second time, immediately following a prior invocation, shall result in NULL being returned." So, I've modified dlerror to do just that. Thanks for bringing this to our attention. cgf
