Function NT_GetValueFloatArray

Source 
pub unsafe extern "C" fn NT_GetValueFloatArray(
    value: *const NT_Value,
    last_change: *mut u64,
    arr_size: *mut usize,
) -> *mut f32
Expand description

Returns a copy of the float array from the NT_Value. If the NT_Value is null, or is assigned to a different type, returns null.

§Parameters

  • value: NT_Value struct to get the float array from.
  • last_change: Returns time in ms since the last change in the value.
  • arr_size: Returns the number of elements in the array.

§Returns

Pointer to the float array, or null if error.

It is the caller’s responsibility to free the array once it’s no longer needed. The NT_FreeFloatArray() function is useful for this purpose. The returned array is a copy of the array in the value, and must be freed separately.
