Hi all,
I am using msg queues in our program and have been for a few years. I have
just recently added a new task with a new queue, and when I call
mq_receive() for this queue it is getting errno 14, EFAULT, meaning bad
address. I can’t find anything in the docs to indicate what this might mean
in relation to mq_receive(). Can anyone shed some light?
Every other message queue (I have 35 other queues) are working perfectly.
We are running mqueue 4.24A on QNX4.25
Regards,
Rodney

EFAULT usually comes from the underlieing Sendfd() call used to implement
mq_receive().
The description is:
EFAULT
In order to complete the message exchange, the current process would
have incurred a segment violation. Your buffer(s) may be invalid or
too small.
So, look for a bad pointer, or too small buffer to your mq_receive().
