Hello, I am newbie in rt programming and i wonder where can i get an example about file handling following the describe idea from rt wiki " File handling .- File handling is known to generate disastrous pagefaults. So, if there is a need for file access from the context of the RT-application, then this can be done best by splitting the application in an RT part and a file-handling part. Both parts are allowed to communicate through sockets. I have never seen a page fault caused by socket traffic. Note: While accessing files the low-level fopen() call will do a mmap() to allocate new memory to the process, resulting in a new pagefault." any sample with rt part and file handle part ? Another question, about java realtime specification, java sun rtsj I wonder, if rt programming (using c) needs to check a lot of elements , faultpages, sockets, etc ... how can it possible that a java programmer can run applications (with a gc collector) and these applications can get a "rt profile" ? is RTSJ a "valid" real time specification? thank you - To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
