<H2>DESCRIPTION</H2>
|
|
|
|
This function converts the logical input string to the visual output
|
|
strings as specified by the Unicode Bidirectional Algorithm. As a side
|
|
effect it also generates mapping lists between the two strings, and the
|
|
list of embedding levels as defined by the algorithm.
|
|
<P>
|
|
If NULL is passed as any of the the lists, the list is ignored and not
|
|
filled.
|
|
<P>
|
|
This function is obsolete because it only handles one-line paragraphs.
|
|
Please consider using other functions instead. Deprecated.
|
|
<A NAME="lbAF"> </A>
|
|
<H2>RETURNS</H2>
|
|
|
|
Maximum level found plus one, or zero if any error occurred
|
|
(memory allocation failure most probably).
