Equivalent and Nearest Equivalent Languages </title><shortdesc>This section describes how to call functions of <apiname>BaflUtils</apiname> to

get an equivalent language list and a nearest equivalent language. </shortdesc><prolog><metadata><keywords/></metadata></prolog><taskbody>

<prereq><p>This tutorial assumes that you have an understanding of the following

topics: </p> <ul>

<li id="GUID-3AECC912-FD5E-5837-BB83-763A6536DA73"><p><xref href="GUID-10A50B7C-63DB-599B-86C1-17989595CBD2.dita">Equivalent

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

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

Application Resources</xref> describes the purpose of resource files. </p> </li>

<context><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>
