- * \file
- * \brief C API: Locale
- *
- * <h2> ULoc C API for Locale </h2>
- * A <code>Locale</code> represents a specific geographical, political,
- * or cultural region. An operation that requires a <code>Locale</code> to perform
- * its task is called <em>locale-sensitive</em> and uses the <code>Locale</code>
- * to tailor information for the user. For example, displaying a number
- * is a locale-sensitive operation--the number should be formatted
- * according to the customs/conventions of the user's native country,
- * region, or culture. In the C APIs, a locales is simply a const char string.
- *
- * <P>
- * You create a <code>Locale</code> with one of the three options listed below.
- * Each of the component is separated by '_' in the locale string.
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- * newLanguage
- *
- * newLanguage + newCountry
- *
- * newLanguage + newCountry + newVariant
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- * The first option is a valid <STRONG>ISO
- * Language Code.</STRONG> These codes are the lower-case two-letter
- * codes as defined by ISO-639.
- * You can find a full list of these codes at a number of sites, such as:
- * <BR><a href ="http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt">
- * http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt</a>
- *
- * <P>
- * The second option includes an additonal <STRONG>ISO Country
- * Code.</STRONG> These codes are the upper-case two-letter codes
- * as defined by ISO-3166.
- * You can find a full list of these codes at a number of sites, such as:
- * <BR><a href="http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html">
- * http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html</a>
- *
- * <P>
- * The third option requires another additonal information--the
- * <STRONG>Variant.</STRONG>
- * The Variant codes are vendor and browser-specific.
- * For example, use WIN for Windows, MAC for Macintosh, and POSIX for POSIX.
- * Where there are two variants, separate them with an underscore, and
- * put the most important one first. For
- * example, a Traditional Spanish collation might be referenced, with
- * "ES", "ES", "Traditional_WIN".
- *
- * <P>
- * Because a <code>Locale</code> is just an identifier for a region,
- * no validity check is performed when you specify a <code>Locale</code>.
- * If you want to see whether particular resources are available for the
- * <code>Locale</code> you asked for, you must query those resources. For
- * example, ask the <code>UNumberFormat</code> for the locales it supports
- * using its <code>getAvailable</code> method.
- * <BR><STRONG>Note:</STRONG> When you ask for a resource for a particular
- * locale, you get back the best available match, not necessarily
- * precisely what you asked for. For more information, look at
- * <code>UResourceBundle</code>.
- *
- * <P>
- * The <code>Locale</code> provides a number of convenient constants
- * that you can use to specify the commonly used
- * locales. For example, the following refers to a locale
- * for the United States:
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- * ULOC_US
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * <P>
- * Once you've specified a locale you can query it for information about
- * itself. Use <code>uloc_getCountry</code> to get the ISO Country Code and
- * <code>uloc_getLanguage</code> to get the ISO Language Code. You can
- * use <code>uloc_getDisplayCountry</code> to get the
- * name of the country suitable for displaying to the user. Similarly,
- * you can use <code>uloc_getDisplayLanguage</code> to get the name of
- * the language suitable for displaying to the user. Interestingly,
- * the <code>uloc_getDisplayXXX</code> methods are themselves locale-sensitive
- * and have two versions: one that uses the default locale and one
- * that takes a locale as an argument and displays the name or country in
- * a language appropriate to that locale.
- *
- * <P>
- * The ICU provides a number of services that perform locale-sensitive
- * operations. For example, the <code>unum_xxx</code> functions format
- * numbers, currency, or percentages in a locale-sensitive manner.
- * </P>
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- * UErrorCode success = U_ZERO_ERROR;
- * UNumberFormat *nf;
- * const char* myLocale = "fr_FR";
- *
- * nf = unum_open( UNUM_DEFAULT, NULL, success );
- * unum_close(nf);
- * nf = unum_open( UNUM_CURRENCY, NULL, success );
- * unum_close(nf);
- * nf = unum_open( UNUM_PERCENT, NULL, success );
- * unum_close(nf);
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- * Each of these methods has two variants; one with an explicit locale
- * and one without; the latter using the default locale.
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- *
- * nf = unum_open( UNUM_DEFAULT, myLocale, success );
- * unum_close(nf);
- * nf = unum_open( UNUM_CURRENCY, myLocale, success );
- * unum_close(nf);
- * nf = unum_open( UNUM_PERCENT, myLocale, success );
- * unum_close(nf);
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- * A <code>Locale</code> is the mechanism for identifying the kind of services
- * (<code>UNumberFormat</code>) that you would like to get. The locale is
- * <STRONG>just</STRONG> a mechanism for identifying these services.
- *
- * <P>
- * Each international serivce that performs locale-sensitive operations
- * allows you
- * to get all the available objects of that type. You can sift
- * through these objects by language, country, or variant,
- * and use the display names to present a menu to the user.
- * For example, you can create a menu of all the collation objects
- * suitable for a given language. Such classes implement these
- * three class methods:
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- * const char* uloc_getAvailable(int32_t index);
- * int32_t uloc_countAvailable();
- * int32_t
- * uloc_getDisplayName(const char* localeID,
- * const char* inLocaleID,
- * UChar* result,
- * int32_t maxResultSize,
- * UErrorCode* err);
- *
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- * <P>
- * Concerning POSIX/RFC1766 Locale IDs,
- * the getLanguage/getCountry/getVariant/getName functions do understand
- * the POSIX type form of language_COUNTRY.ENCODING\@VARIANT
- * and if there is not an ICU-stype variant, uloc_getVariant() for example
- * will return the one listed after the \@at sign. As well, the hyphen
- * "-" is recognized as a country/variant separator similarly to RFC1766.
- * So for example, "en-us" will be interpreted as en_US.
- * As a result, uloc_getName() is far from a no-op, and will have the
- * effect of converting POSIX/RFC1766 IDs into ICU form, although it does
- * NOT map any of the actual codes (i.e. russian->ru) in any way.
- * Applications should call uloc_getName() at the point where a locale ID
- * is coming from an external source (user entry, OS, web browser)
- * and pass the resulting string to other ICU functions. For example,
- * don't use de-de\@EURO as an argument to resourcebundle.
- *
- * @see UResourceBundle
