At least on Open Solaris[1], nftw() is safe in multithreaded applications as long as you don't use FTW_CHDIR[2]. It doesn't use static data, and instead passes around pointers to 'struct Var' and 'struct Save' that are allocated on the stack. See ftw(3C) and $SRC/lib/libc/port/gen/nftw.c for details. [1] We're still talking about Open Solaris, right? ;-} [2] The inherent problems with chdir should be obvious. -- James Carlson, KISS Network <james.d.carlson at sun.com> Sun Microsystems / 1 Network Drive 71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677
