* arrays_javascript.i
|
|
*
|
|
* These typemaps give more natural support for arrays. The typemaps are not efficient
|
|
* as there is a lot of copying of the array values whenever the array is passed to C/C++
|
|
* from JavaScript and vice versa. The JavaScript array is expected to be the same size as the C array.
|
|
* An exception is thrown if they are not.
|
|
*
|
|
* Example usage:
|
|
* Wrapping:
|
|
*
|
|
* %include <arrays_javascript.i>
|
|
* %inline %{
|
|
* extern int FiddleSticks[3];
|
|
* %}
|
|
*
|
|
* Use from JavaScript like this:
|
|
*
|
|
* var fs = [10, 11, 12];
|
|
* example.FiddleSticks = fs;
|
|
* fs = example.FiddleSticks;
