Get the indexes of the selected items
unsigned short *PtGenListGetSelIndexes( PtWidget_t *widget, unsigned short *buffer );
This function fills the given buffer with the indexes of the currently selected items. The first item in the list has an index of 1, not 0.
If buffer is NULL, the function allocates a buffer using malloc(), and terminates the buffer with a zero. It's your application's responsibility to free the buffer when it's no longer needed.
If buffer isn't NULL, the function adds a 0 to the end only if there are no selected items.
A pointer to the buffer.
