MPI_Register_datarep function
Register a set of user-provided data conversion functions.
Syntax
int MPIAPI MPI_Register_datarep(
_In_ char *datarep,
_In_opt_ MPI_Datarep_conversion_function *read_conversion_fn,
_In_opt_ MPI_Datarep_conversion_function *write_conversion_fn,
_In_ MPI_Datarep_extent_function *dtype_file_extent_fn,
_In_opt_ void *extra_state
);
Parameters
datarep [in]
Data representation identifier.read_conversion_fn [in, optional]
Function invoked to convert from file representation to native representation.write_conversion_fn [in, optional]
Function invoked to convert from native representation to file representation.dtype_file_extent_fn [in]
Function invoked to get the extent of a datatype as represented in the file.extra_state [in, optional]
Extra state that is passed to the conversion functions.
Return value
Returns MPI_SUCCESS on success. Otherwise, the return value is an error code.
In Fortran, the return value is stored in the IERROR parameter.
