Dear Listmembers
First of a simple question most of you can propably answer:
* Is operations on the fifos "atomic"?
Both in userspace and in the rtkernel?
* Where can I find SSIZE_MAX [MAX bytesize for read()/write()] on an i3x86
2.2.18/19?
* What is the max size of an fifo-queue?
And unless it fails on initialisation there was enough
kernelmemory - right?
* Are there an "RTL_SSIZEMAX" for operations on the rtl_fifos?
For some reason if havent been able to find any place in the manpages that
states that the RTFIFOs are Atomic, though the fifos work as if they were
...

Next up is a problem with a simpel POSIX_thread:
For some reason my thread keep chrashing the system [both in
2.2.18-rtlv3.0 and 2.2.19-rtlv3.1pre3]. I've been looking over the code
throughly, and it seems allright. There's no dynamic memoryallocation, and
only some simple IO to hardcoded adresses. I.e. it shouldnt chrash due to
pointer-error or memory-leaks.
However the thread uses some quite large variables, that according to my
memmory are allocated on the stack (?).
How can I tell if the stack runs out [has run out - overwrite kernelspace
- whatever], and how can I increase the size
dynammicly?

Hmm, maybe I should have spilt the mail i two - nahh I'll send you some
other questions instead :-)
