Blocking read call never returns to bison parser. Hi All, I have written a flex/bison scanner and parser to read data output of a legacy network switch. I wrote the parser as a standalone program and tested it with sample output saved to text file (e.g., cat data.out | ./parser). My issue is, having confirmed that my parser is valid, I am integrating it int... 24 Jun 2008 18:30
mmap(MAP_SHARED) and msync(MS_INVALIDATE) Dear Experts, I have a program which mmap()s its read-mostly data file. If I run two instances of the program concurrently, I want the changes made by one to be visible to the other. So I call mmap with the MAP_SHARED flag. After I make a change to the data I call msync(). Since I'm using MAP_SHARED I ... 26 Jun 2008 23:52

loopback test on serial port. Default termios config Hi, I'm wondering if you've had any success with fixing your problem. I'm trying to setup a simple loopback test on Redhat and it says writes to the ttyS0 port are fine, but it never reads back from it. I've tried your code, my code, and other simple code that I found online .... none of them have been able to read... 20 Jun 2008 19:27

multiple definition at link time Hello to everybody, I'm wondering if someone can show me a workaround to the following problem I'm fighting with. In my program I need to use two libraries: ARPACK and PARDISO. Both of them make (internal) use of a third library, namely LAPACK. Unfortunately they use a different version of this library. I hav... 20 Jun 2008 06:05
How long does read(2) wait before an EAGAIN is thrown? For example, I send a greeting message to smtp-server, and expect to read an SMTP ``250'' response. How long time does read() wait before a slow 250 arrives, if this runs on non-blocking i/o? // greeting sbuf = "HELO " + server + "\n"; cout << sbuf; if (write(sock, sbuf.c_str(), sbuf.size()) < 0){ perr... 26 Jun 2008 18:45
