Hi, I have a very simple program. It basically tries to open a message queue which does not exists. mq_open returns then -1 but errno is set to 78 which is defined as this: #define ENOSYS 78 /* Function not implemented */ The line in question: res = mq_open ("/doesnotexist", O_RDWR); "/doesnotexists" is the non-existing message queue the program tests for. res will be set correctly to -1 but errno is set then to 78. If I want to create the message queue, I will get the same error. uname -a says: FreeBSD X220.alogt.com 10.1-PRERELEASE FreeBSD 10.1-PRERELEASE #45 r271420: Sat Sep 13 15:09:34 WITA 2014 erich@X220.alogt.com:/usr/obj/usr/src/sys/X220 amd64 Do I see or do something wrong or is this an error? Erich
