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) status - status object (Status)
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', 'MPI_File') are of type 'INTEGER' in Fortran. 8/31/1998 MPI_File_read_all(3)
