Documentation

This is a convenience function that does not use a UBiDi object. It is intended to be used for when an application has determined the levels of objects (character sequences) and just needs to have them reordered (L2). This is equivalent to using ubidi_getVisualMap on a UBiDi object.

Parameters:

levels - is an array with length levels that have been determined by the application.
length - is the number of levels in the array, or, semantically, the number of objects to be reordered. It must be length>0.
indexMap - is a pointer to an array of length indexes which will reflect the reordering of the characters. The array does not need to be initialized.

The index map will result in indexMap[visualIndex]==logicalIndex.
