<prereq id="GUID-03EE02F1-492A-463A-A64B-9BA086897FAE"><p>This tutorial

assumes that you have an understanding of <xref href="GUID-10A50B7C-63DB-599B-86C1-17989595CBD2.dita">Equivalent Language

Reference</xref> which explains the equivalent language table, including

the equivalent language list and its priority.</p> </prereq>

<context id="GUID-11BBC0DD-7E59-423E-81C3-39FA5E5943C4"><p> <xref href="GUID-5F9CAA3E-D8BF-3488-9797-3B9FB4452930.dita"><apiname>BaflUtils</apiname></xref> provides the following two static functions to

get the equivalent language list and a nearest equivalent language: </p> <ul>

<li id="GUID-42B035C0-34C1-585E-8195-B317C694018C"><codeblock id="GUID-0686FF33-BE2D-597C-8CC7-422AE32F1554" xml:space="preserve">GetEquivalentLanguageList(TLanguage aLang, TLanguagePath&amp; aEquivalents)</codeblock> <p>For a given language (<xref href="GUID-698538DF-DCDC-347B-BD32-DD9EB896BAFB.dita"><apiname>TLanguage</apiname></xref>), it returns

an array (<xref href="GUID-2533E3D6-D0D8-3638-847D-C5DED07557BD.dita"><apiname>TLanguagePath</apiname></xref>) which contains the equivalent

languages. If no equivalent language is found, <codeph>ELangNone</codeph> is returned. </p> </li>

<li id="GUID-B2CBF4AA-9F96-59E7-BBD1-C069FEF0EACD"><codeblock id="GUID-6C39809C-E824-52B1-8E87-6EE36F333E4D" xml:space="preserve">NearestLanguageFileV2(const RFs&amp; aFs,TFileName&amp; aName, TLanguage&amp; aLanguage)</codeblock> <p>A <xref href="GUID-698538DF-DCDC-347B-BD32-DD9EB896BAFB.dita"><apiname>TLanguage</apiname></xref> value is used at the end of a

resource file name to identify a resource file for a language. For

example, <filepath>filename.r01</filepath> and <filepath>filename.r02</filepath> are the English and French versions of the <filepath>filename.rsc</filepath> resource file. </p> <p>An application calls <codeph>BaflUtils::NearestLanguageFileV2()</codeph> to determine which localized resource file is the closest to the

current system language. The function searches the following drives

in the given sequence for the available resource files, which have

the same file name (without extension) as <codeph>aName</codeph>.

Once the resource files are searched on a drive, the function stops

searching on the next drive. </p> <ul>

<li id="GUID-8BD6E006-7369-559A-AD7E-7192E7F2C400"><p>The custom resource

drive if it is set using the <codeph>HAL::ECustomResourceDrive</codeph> attribute or the legacy <codeph>HAL::ESystemDrive</codeph> attribute. </p> </li>

<li id="GUID-E361606A-6E26-5E25-9C0E-429047947BB4"><p>The optional

drive if it is specified in the <codeph>aName</codeph> parameter. </p> </li>

<li id="GUID-D905BA6F-72BE-535E-8225-0018F08E4EAB"><p> <filepath>Z:</filepath> drive if the optional drive is not set in the <codeph>aName</codeph> parameter. </p> </li>

</ul> <p>The current system language is then taken as a given language.

All the available resource file names are prioritized according to

the <xref href="GUID-10A50B7C-63DB-599B-86C1-17989595CBD2.dita">equivalent

language list</xref>. The resource file name with the highest priority

is returned. </p> </li>

</ul> </context>
