>Modern Unixes have a call to tell you the # of file descriptors: > count = getdtablesize(); Mmph. Note that under SunOS 4.1, getdtablesize() can return something that's less than the number of open files. File descriptors are now a resource affected by getrlimit/setrlimit. getdtablesize returns the current soft limit on number of file descriptors. To ensure that all file descriptors get closed, you should use the hard limit instead. -- Felix Lee flee@cs.psu.edu
