NAME

       MPI_File_preallocate -  Preallocates storage space for a file

SYNOPSIS

       int MPI_File_preallocate(MPI_File fh, MPI_Offset size)

INPUT PARAMETERS

       fh     - file handle (handle)
       size   - size to preallocate (nonnegative integer)

NOTES FOR FORTRAN

       All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the
       end of the argument list.  ierr is an integer and has the same meaning as the return value of the routine
       in C.  In Fortran, MPI routines are subroutines, and are invoked with the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.
