file2sm - shared-memory linked list data ingestion test program

       Report bugs to <ion-bugs@korgano.eecs.ohiou.edu>

file2sm stress-tests shared-memory linked list data ingestion by repeatedly writing all text lines of the
       file named fileName to a shared-memory linked list that is the root object of a PSM partition named
       "file2sm".

       After writing each line to the linked list, file2sm gives a semaphore to indicate that the list is now
       non-empty.  This is mainly for the benefit of the complementary test program sm2file(1).

       The operation of file2sm is cyclical.  After copying all text lines of the source file to the linked
       list, file2sm appends an EOF line to the linked list, containing the text "*** End of the file ***", and
       prints a brief performance report:

               Processing I<lineCount> lines per second.

       Then it reopens the source file and starts appending the file's text lines to the linked list again.

       Can't attach to shared memory
           Operating system error.  Check errtext, correct problem, and rerun.

       Can't manage shared memory.
           PSM  error.  Check for earlier diagnostic messages describing the cause of the error; correct problem
           and rerun.

       Can't create shared memory list.
           smlist error.  Check for earlier diagnostic messages describing  the  cause  of  the  error;  correct
           problem and rerun.

       Can't create semaphore.
           ION  system  error.  Check for earlier diagnostic messages describing the cause of the error; correct
           problem and rerun.

       Can't open input file
           Operating system error.  Check errtext, correct problem, and rerun.

       Can't reopen input file
           Operating system error.  Check errtext, correct problem, and rerun.

       Can't read from input file
           Operating system error.  Check errtext, correct problem, and rerun.

       Ran out of memory.
           Nominal behavior.  sm2file is not extracting data from the linked list quickly enough to  prevent  it
           from growing to consume all memory allocated to the test partition.

       No environment variables apply.

       "0" file2sm has terminated.

       No configuration files are needed.
