      Hi all,
      If We are excuting shell command in c program. then how can we get result of that command in variable?

      For example:
      int var;
      var=system(“uname -r”);

      This command gives OS version , But in var variable it gives exit status of that command.
      But I want the OS version in variable.How can we get that?

      Any idea?

      Thanks in advance,
