[PATCH] set FD_CLOEXEC properly when O_CLOEXEC is not supported

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



FD_CLOEXEC only applies to the file descriptor, so it needs to be
manipuluated via F_GETFD/F_SETFD.  F_GETFL/F_SETFL are for file
description flags.

Verified via strace with o_cloexec set to zero.
