Hi everyone!
I'm trying to understand and use all the process creation (spawn, fork) and IPC (pipes, shared memory and stuff) tools that QNX offers, which, unless i'm not getting the concept right, I think are what gives QNX the "real time" part... am I wrong?:$...
My problem is that, since all those concepts are kind of abstract (at least for me) I'm having troubles finding the way to use them in a real application... Does anybody know or has an application code, or know where i can find one that helps me deal with this? or a tutorial (besides the one that comes with QNX help), anything... i would really appreciate it... Thanks in advance!
Antonio |

Yes. Linux and Windows have similar concept and yet they aren't as real time as QNX.
It their implementation that makes them real-time. Yet they can't make miracles and won't make a bad design real-time ;-) |

| Somebody knows where to get a cheaper version? This seems to be a kind of antique ^^ |

| Cheaper version of the books? I see that they indicate that the books are unavailable. You might want to try contacting Robert to see if he knows where they can be obtained. I recall talking to him a year or so ago, and I think that the rights to one of the books was bought out by QNX, although they were taking their time about getting it reprinted. And there is always eBay. I think someone might have snatched up the remaining copies in order to profit. |
