MPI_Register_datarep - Register functions for user-defined data representations
int MPI_Register_datarep(ROMIO_CONST char *datarep, MPI_Datarep_conversion_function * read_conversion_fn, MPI_Datarep_conversion_function * write_conversion_fn, MPI_Datarep_extent_function * dtype_file_extent_fn, void *extra_state)
This function allows the user to provide routines to convert data from an external representation, used within a file, and the native representation, used within the CPU. There is one predefined data representation, external32 . Please consult the MPI-2 standard for details on this function.
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.
