NAME
       MPI_File_read_shared  -  Reads  a  file  using  the shared file pointer
       (blocking, noncollective).
SYNTAX
       C Syntax
           #include <mpi.h>
           int MPI_File_read_shared(MPI_File fh, void *buf, int count,
       MPI_Datatype datatype, MPI_Status *status)
       Fortran Syntax
           INCLUDE 'mpif.h'
           MPI_FILE_READ_SHARED(FH, BUF, COUNT, DATATYPE, STATUS,
            IERROR)
                 <TYPE>         BUF(*)
                 INTEGER        FH, COUNT, DATATYPE,
                           STATUS(MPI_STATUS_SIZE), IERROR
C++ Syntax
       #include <mpi.h>
       void MPI::File::Read_shared(void* buf, int count,
            const MPI::Datatype& datatype, MPI::Status& status)
       void MPI::File::Read_shared(void* buf, int count,
            const MPI::Datatype& datatype)
INPUT/OUTPUT PARAMETER
       fh        File handle (handle).
INPUT PARAMETERS
       count     Number of elements in buffer (integer)
       datatype  Data type of each buffer element (handle).
OUTPUT PARAMETERS
       buf       Initial address of buffer (choice).
       status    Status object (status).
       IERROR    Fortran only: Error status (integer).
DESCRIPTION
       MPI_File_read_shared is a blocking routine that uses  the  shared  file
       pointer  to read files. The order of serialization is not deterministic
       for this noncollective routine.
ERRORS
       Almost all MPI routines return an error value; C routines as the  value
       of  the  function  and Fortran routines in the last argument. C++ func-
       tions do not return errors. If the default  error  handler  is  set  to
       MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism
