Dear Jan, I had already read that webpage, but I dont need to change the data on that file. I just want to create a new file and then close it, so I can use it later in another system call, to mmap it to a user space. Is it clearer now? Can you please give me some code snippet? Thanks again in advance and greetings! Rafael Sisto.
