      Thanks,

    Ulimit gives 1024 as open file limit. In struct task_struct it has a
    member called struct files_struct *files;

    
    I tried checking for this member and the limit however I am  not
    able to decide correctly why the limit is 1024.

     Also, is there any distinction between 32 bit and 64 bit systems
    for this limit?

                What is the Max no of files that can be opened
                simultaneously within a Single C program.

                
                i want this information for kenel compilation

                
            See man 3 setrlimit

              Total number of files that can be opened should depend on
              file system.

              And what this has to do with kernel compilation?
