MPI_File_preallocate(3)               MPI              MPI_File_preallocate(3)

NAME
       MPI_File_preallocate -  Preallocates storage space for a file

SYNOPSIS
       int MPI_File_preallocate(MPI_File mpi_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.
