[zeromq-dev] MSG_DONTWAIT on AIX/HP-UX

[Tamara Kustarova]

Hello Stephen,

thank you for info on MSG_DONTWAIT. Currently we replaced MSG_DONTWAIT
with fcntl function, to set socket to nonblocking mode. We use
O_NONBLOCK constant, as it works on all tested platforms. It was tested
on Linux, Solaris, FreeBSD, OpenBSD, Qnxnto, Mac OsX. Windows
implementation remains the same using ioctlsocket() function. 
The code can be found in revision 617. 
If you experience any problems using this, let us know, please.

Tamara
