Function starpu_variable_data_register 

pub unsafe extern "C" fn starpu_variable_data_register(
    handle: *mut starpu_data_handle_t,
    home_node: c_int,
    ptr: usize,
    size: usize,
)

Register the \p size byte element pointed to by \p ptr, which is typically a scalar, and initialize \p handle to represent this data item.

Here an example of how to use the function. \code{.c} float var = 42.0; starpu_data_handle_t var_handle; starpu_variable_data_register(&var_handle, STARPU_MAIN_RAM, (uintptr_t)&var, sizeof(var)); \endcode
