MPI_Win_copy_attr_function callback function
MPI_Win_copy_attr_function is a placeholder for the application-defined function name. It is a copy callback function for win_keyval.
Syntax
int MPI_Win_copy_attr_function(
MPI_Win oldwin,
int win_keyval,
_In_opt_ void *extra_state,
_In_ void *attribute_val_in,
_Out_ void *attribute_val_out,
_Out_ int *flag
);
Parameters
oldwin
Old MPI window.win_keyval
Window key value.extra_state [in, optional]
Extra state.attribute_val_in [in]
Input value of the attribute.attribute_val_out [out]
Output value of the attribute.flag [out]
Flag value indicating if the copy was successful.
Return value
If an attribute copy function returns anything other than MPI_SUCCESS, then the call that caused it to be invoked is erroneous.
