p.mq_msgsize); mq_close(t); return 0; } Program output is as follows: tarr@BSDINC-16W>> ./qtest.exe Failed to create /stuff queue - 2 See if the queue entry was created: tarr@BSDINC-16W>> ls -al /dev/mqueue/stuff -rw-rw-rw- 1 tarr None 82176 Jul 8 12:04 /dev/mqueue/stuff Try again: tarr@BSDINC-16W>> ./qtest.exe Failed to create /stuff queue - 0 Note - 1: Machine is a 64 bit running 64bit Windows 7 tarr@BSDINC-16W>> uname -aCYGWIN_NT-6.1-WOW64 BSDINC-16W 1.7.20(0.266/5/3) 2013-06-07 11:11 i686 Cygwin
