NAME
       MPI_File_read_all_begin -  Begin a split collective read using individual file pointer

SYNOPSIS
       int MPI_File_read_all_begin(MPI_File mpi_fh, void *buf, int count,
				   MPI_Datatype datatype)

INPUT PARAMETERS
       fh     - file handle (handle)
       count  - number of elements in buffer (nonnegative integer)
       datatype
	      - datatype of each buffer element (handle)

OUTPUT PARAMETERS
       buf    - initial address of buffer (choice)

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.
