Hi all,

i have a question about /dev/(u)random.

In qnx documentation it is said, that urandom is not blocking due to a fallback to an internal prng. i guess this 
implicitly means that random can block.

Now in the sourcecode of random service i was not able to find that both devices are handled different.

Could someone please explain how these two devices are working and if one of them is blocking?

I have a qnx 6.5 system here for testing and was able to get about 500 KByte/s. so i don't have the impression that 
there is a difference between both devices and that one of them is blocking.

random service has been started with -t for clock as data source.

Thanks a lot.
