msgrcv gets error ENXIO

[mmque]

I have an application runing on AIX which has two threads. One thread is getting message from a queue in a loop using msgrcv(). I got many errors indicates the msgrcv() failed with error ENXIO (6). This error is not listed in the man page of msgrcv(). Can somebody tell me why I got such error.

Thanks.

You'll get ENXIO if you don't have read privileges to the message queue. Check the read/write permissions you are creating the messge queue with.

Good Luck.
