       const FriBidiStrIndex len
              Input string length of the paragraph.

       FriBidiParType *pbase_dir
              Requested and resolved paragraph base direction.

              Possible values for a FriBidiParType are as follows:
               FRIBIDI_PAR_LTR   Left-To-Right paragraph.
               FRIBIDI_PAR_RTL   Right-To-Left paragraph.

               FRIBIDI_PAR_WRTL  Weak Right To Left paragraph.

       FriBidiLevel *embedding_levels
              Output list of embedding levels.


       This function finds the bidi embedding levels of a single paragraph, as
       defined  by  the   Unicode   Bidirectional   Algorithm   available   at  This function implements rules P2
       to I1 inclusive, and parts 1 to 3 of L1, except for rule  X9  which  is
       implemented   in   fribidi_remove_bidi_marks().    Part   4  of  L1  is
       implemented in fribidi_reorder_line().

       There are a few macros defined in  fribidi-bidi-types.h  to  work  with
       this embedding levels.


       Maximum  level  found  plus  one,  or zero if any error occured (memory
       allocation failure most probably).
