It might under some circumstances but not directly. It has 3 sub interfaces, if there is an error on one the the DAQ program will call abort() which would result in FDs being closed. However that sub interface does not use read/poll only ioctl. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C
