posix message queues

[Lisa A. Day]

Hi All,
I'm experiencing some oddities with the posix msqs, which I'm hopefully 
missing some simple tips to overcome (hopefully not missing the point 
all together) .
1)  In my app, the API is extremely picky about names - "/" plus 6 
characters -- only. Is this correct? I can deal with it, but it took 
some time to figure it out.
2) I can spawn mulitple threads from the POSIX_init process no problem, 
but I can't spawn a thread from one of its child processes. Is there a 
trick or caveat to accomplishing this?

Thanks - and if anyone knows of some good tech notes or documentation 
for this API that I haven't found, that would be helpful...
