errno is an implicit global variable set/modified by almost all runtime APIs in case of an error. In our case errno is set/modified in the ::dlopen() call. So the logic is first reset errno to 0 (no error), then call the API (here ::dlopen) which will set errno in case of an error with one of the values described in the APIs man-page, and directly after the API call but at least before the next API call save the content of errno into a local variable for further evaluation (here we return the value of eno to your function for the eno == ENOENT check).
