NAME

       fribidi_get_par_embedding_levels_ex - get bidi embedding levels of a paragraph

SYNOPSIS

       #include <fribidi.h>

       extern FriBidiLevel fribidi_get_par_embedding_levels_ex
       (
            const FriBidiCharType *bidi_types,
            const FriBidiBracketType *bracket_types,
            const FriBidiStrIndex len,
            FriBidiParType *pbase_dir,
            FriBidiLevel *embedding_levels
       );

PARAMETERS

       const FriBidiCharType *bidi_types
              Input list of bidi types as returned by fribidi_get_bidi_types().

              Since  there  are  23 possible values for a const FriBidiCharType, they are not all
              listed here.

       const FriBidiBracketType *bracket_types
              Input list of bracket types as returned by fribidi_get_bracket_types().

       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_ON    DirectiOn-Neutral paragraph.
              FRIBIDI_PAR_WLTR  Weak Left To Right paragraph.
              FRIBIDI_PAR_WRTL  Weak Right To Left paragraph.

       FriBidiLevel *embedding_levels
              Output list of embedding levels.

DESCRIPTION

       This function finds the bidi embedding levels of a single paragraph,  as  defined  by  the
       Unicode  Bidirectional  Algorithm  available at http://www.unicode.org/reports/tr9/.  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.

RETURNS

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