On a POSIX (or GNU) system, what can make the dlclose() function fail?
I know that it fails on repeat-close; and that it misbehaves on a null pointer argument (got a segmentation violation on my system). But are there other situations it can fail?
Edit: I tried looking at the source code and was kind of stumped - could not really figure out where to look (dlclose.c is not the place apparently).
The actual implementation is here.
Look for calls to
_dl_signal_error()-- there are two.
