MPI_Type_copy_attr_function callback function
MPI_Type_copy_attr_function is a placeholder for the application-defined function name.
Syntax
int MPI_Type_copy_attr_function(
MPI_Datatype olddatatype,
int datatype_keyval,
_In_opt_ void *extra_state,
_In_ void *attribute_val_in,
_Out_ void *attribute_val_out,
_Out_ int *flag
);
Parameters
olddatatype
Old datatype.datatype_keyval
Key value to copy.extra_state [in, optional]
Extra state.attribute_val_in [in]
Input attribute value.attribute_val_out [out]
Output attribute value.flag [out]
Value indicating the success of the copy operation.
Return value
If an attribute copy function returns something other than MPI_SUCCESS, then the call that caused it to be invoked (for example, MPI_Type_create_keyval), is erroneous.
