MPI_File_read_all - Uses individual file pointer to
       perform a collective read


SYNOPSIS

       C:

            #include "mpi.h"

            int MPI_File_read_all(MPI_File fh, void *buf, int count,
            MPI_Datatype datatype, MPI_Status *status)

       Fortran:

            INCLUDE "mpif.h" (or USE MPI)

            <type> BUF(*)
            INTEGER fh, count, datatype, status(MPI_STATUS_SIZE),
            ierror

            CALL MPI_FILE_READ_ALL(fh, buf, count, datatype,
            status, ierror)


DESCRIPTION

       MPI_File_read_all is a collective version of the blocking
       MPI_File_read interface. MPI_File_read_all accepts the
       following arguments:

       fh        Specifies the file handle (handle)

       count     Specifies the number of elements in the buffer
                 (nonnegative integer)

       datatype  Specifies the data type of each buffer element
                 (handle)

       buf       Returns the initial address of the buffer
                 (choice)

       status    Returns the status object (status)

       ierror    Specifies the return code value for successful
                 completion, which is in MPI_SUCCESS.
                 MPI_SUCCESS is defined in the mpif.h file.

   Notes for Fortran
       All MPI objects (for example, MPI_Datatype, MPI_Comm,
       MPI_File) are of type INTEGER.
