It seems like a minor point that won't be noticed until it causes a problem, and problems are rare enough they might go unnoticed for a while. We have removed system() from our application, but we're also concerned that libraries we integrate will use system() without our knowledge. Reimplementing system() is trivial. LD_LIBRARY_PRELOAD should take care of all system(3) calls. I wonder it it has some value to add runtime checking for "multi-threaded" to such lib functions and error out if yes. Apart from that, system() is a PITA even on single/non-threaded apps. MfG, Bernd -- There is no cloud, just other people computers. -- https://static.fsf.org/nosvn/stickers/thereisnocloud.svg
