You can use command ulimit -a, there you can check the limit for a

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?
