Red Hat Bugzilla – Bug 5046
send(2) manpage lists not supported option
Last modified: 2008-05-01 11:37:51 EDT
Enables non-blocking operation; if the
would block, EAGAIN is returned.
This send*(2) option is not suported in 2.2 kernels.
MSG_DONTWAIT is part of POSIX 1003.1g, and should be documented.
later kernels will implement it.
