Hi, according to the flock(2) man page, flock should return EWOULDBLOCK when a file is locked and the LOCK_NB flag was selected. But on hppa, it seems to return EAGAIN which is not the same. Where is the bug here? In the kernel, glibc, or manpages-dev? This causes problems in apr since it only checks for EWOULDBLOCK. Cheers, Stefan
