Not what you want. Remember that Unix doesn't necessarily do exclusive opens -- quite the contrary if it can get away with it. If you want it sequenced, then you need to do one, then the next, then the next. This is one of the reasons why I suggested cat in the first place -- it implements that guarantee, but it does so as part of the application logic. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
