fribidi_remove_bidi_marks(3)

NAME
fribidi_remove_bidi_marks - remove bidi marks out of an string

SYNOPSIS
#include <fribidi.h>

extern FriBidiStrIndex fribidi_remove_bidi_marks
(
    FriBidiChar *str,
    const FriBidiStrIndex len,
    FriBidiStrIndex *positions_to_this,
    FriBidiStrIndex *position_from_this_list,
    FriBidiLevel *embedding_levels
);

PARAMETERS

FriBidiChar *str
    Input string to clean.

const FriBidiStrIndex len
    Input string length.

FriBidiStrIndex *positions_to_this
    List mapping positions to the order used in str.

FriBidiStrIndex *position_from_this_list
    List mapping positions from the order used in str.

FriBidiLevel *embedding_levels
    List of embedding levels.

DESCRIPTION
This function removes the bidi and boundary-neutral marks out of an string and the accompanying lists. It implements rule X9 of the Unicode Bidirectional Algorithm available at http://www.unicode.org/reports/tr9/#X9, with the exception that it removes U+200E LEFT-TO-RIGHT MARK and U+200F RIGHT-TO-LEFT MARK too. If any of the input lists are NULL, the list is skipped. If str is the visual string, then positions_to_this is positions_L_to_V and position_from_this_list is positions_V_to_L; if str is the logical string, the other way. Moreover, the position maps should be filled with valid entries. A position map pointing to a removed character is filled with -1. By the way, you should not use embedding_levels if str is visual string. For best results this function should be run on a whole paragraph, not lines; but feel free to do otherwise if you know what you are doing.

RETURNS
New length of the string, or -1 if an error occurred (memory allocation failure most probably).
