The following example program SEGVs in dirfd() in libc. Based on the manpage, it should be returning
-1.
#include <sys/types.h>
#include <dirent.h>
#include <stdlib.h>
int
main() {
int fd = dirfd(NULL);
}

That seems very illogical. It would seem to make much more sense to return -1 and set errno to EBADF. -- What |Removed |Added ---------------------------------------------------------------------------- Status|RESOLVED |REOPENED Resolution|INVALID | http://sourceware.org/bugzilla/show_bug.cgi?id=5605 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ^ permalink raw reply [flat|nested] 5+ messages in thread
