fribidi_get_par_embedding_levels_ex - get bidi embedding levels of a paragraph
#include <fribidi.h>

(
const FriBidiCharType *bidi_types,
const FriBidiBracketType *bracket_types,
const FriBidiStrIndex len,

);
Since there are 23 possible values for a const FriBidiCharType, they are not all listed here.
Possible values for a FriBidiParType are as follows:
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.
Maximum level found plus one, or zero if any error occurred (memory allocation failure most probably).
