This ends up opening fd (for openat), a successful stat of fd (for fstatat), etc, instead of failing with ENOENT. #include <fcntl.h> int main() { int fd = open (".", O_RDONLY); if (openat (fd, "", O_RDONLY) != -1 || errno != ENOENT) puts ("failed"); return 0; } -- Summary: openat (and *at friends) fail to detect ENOENT Product: glibc Version: 2.10 Status: NEW Severity: normal Priority: P2 Component: libc AssignedTo: drepper at redhat dot com ReportedBy: ebb9 at byu dot net CC: glibc-bugs at sources dot redhat dot com http://sourceware.org/bugzilla/show_bug.cgi?id=10609 ------- 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] 3+ messages in thread
