Hi Manal, > then I get this in the run time: The call was interrupted by a signal handler. It sounds like your signal handler is violating the very limited constraints of what a signal handler can do. Take a look at your sigaction constraints in your "man sigaction". That lists which functions can be called from within a signal handler. My bet is that the signal handler is using routines (directly or indirectly) not in that list. I strongly recommend that the signal handler be written in such a way as to minimize the signal interruption. For my own, I usually just set a flag and return, and then act upon that flag in the main code at an appropriate time. HTH, --Eljay
