Question on select behaviour
Hi,
I have some specific hardware here and the driver does not seem to support select calls on the filedescriptor as far as I can see (driver does not contain poll()). Now if I try to use the descriptor in a select call, it returns without changing the fd_sets but also returns no error. Is that how it is intended to behave? Any advise would be appreciated. exman |
Ok I found the answer myself.
