When I use dlopen(hDLL) to open a shared library, spin shows me that I have
created a new fd. When I use dlclose(hDLL) to free the handle, I don’t see
the fd count drop in spin.I don’t have any errors associated wiith the open
or close calls. Do I need to do something additional to remove the fd?
Thanks,

Hi Dave,
I believe what you see is a deception 
. Most likely the fd that appears is a result of some open(), which is probably called from another thread while you opening shared library. I think it is just coincidence.
Just in case try sin -P fd
The dlopen() never keeps dll file open. By the time when program returns from dlopen(), the dll fd is closed already. dlclose() only frees memory.
Sincerely,
Serge

Serge,
Thanks for the suggestion to use sin. I noticed in the “use” info that
sin reports itself to be a photon application, while in the RTP utilities
help section of our documentation, sin is a text program. Are there two
versions? I’m curious because our version, at /bin/sin, hangs every time I
try to use it. I don’t have photon on any of the computers, so I don’t know
what might be happening via graphics.
Thanks,
Dave

Dave,
There was a problem with sin usage. I’m not sure in what version. Probably in 6.1A. In 6.2 it’s gone.
