Problem Statement: Handling the file descriptors(opening looping through closing )

                   ...in a common-way
 
                   for routines across a library ...some-thing that which

                   cannot be accomplished by using include directives

                   
Opportunity : 
              Understanding the eval block or sub in quite
              a few programming languages ...or the read block in cobol.


              understand the context

 
              Example: Most or many kind of events or messages are logged

                       ...a process listening on a log file ...

                       ex: tail -f command  ...viz. envisagable on the lines


                           while ( currentoffsetfrombegningoffile <= size(file)){

                                    if(var==EOF ){ set pointer= a byte(location) below EOF)

                           }


              viz. handling of the stdout, stderr, stdin descriptors ...also
                   refer to some of the works performed by this author at 
                   veritas software corp ...viz. in perl ...also as articulated
                   in the document referred below viz. projects.pdf




Note: The above problem statement having been encountered in various scenarios
      and detailed in various 'Proof of concepts' as mentioned in 
      
       http://uk.geocities.com/ravivenkatus/projects.pdf
       http://ravishankarkv.tripod.com/projects.pdf
        ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
