Hi,

Quoting from the post "What OS are you using?
- Try looking at the documentation for mq_open for your OS. It should detail what conditions cause the EFAULT error.
- Also, did you try running the code with a different queue name? do you get the same error every time? "

My os details are as follows Fedora Sulphur
Code:
Linux myMachine 2.6.25-14.fc9.i686 #1 SMP Thu May 1 06:28:41 EDT 2008 i686 i686 i386 GNU/Linux.

Regarding that mq_attr, i changed that to null thinking that it may be the reason for the error. But giving NULL also is throwing the same name.

I even tried changing the name of the queue.Then also it is giving the same error

Could you please try to create a minimalistic program that compiles and shows your particular problem? Otherwise, I'll look tomorrow evening in more details your answer.

Hi Loic,
I tried to write a simple program by just calling the mq_open method.. then also i am getting the same error. Thank you for your valuable time..Kindly help me to get out of this.. One thing I noticed is if i use a msgget() method to create a new message queue it is working fine.. can i use it in program.. can u pls tell me the difference between both.
regards,
paru.

I think, it is best when you post this simple program.

TIA,
Loïc
