Function Documentation

◆ ulocdata_close()

U_CAPI void ulocdata_close ( ULocaleData * uld )

Closes a locale data object.

Parameters

uld	The locale data object to close

Stable:: ICU 3.4

◆ ulocdata_getCLDRVersion()

U_CAPI void ulocdata_getCLDRVersion	(	UVersionInfo	versionArray,
		UErrorCode *	status
	)

Return the current CLDR version used by the library.

Parameters

versionArray	fill-in that will receive the version number
status	error code - could be U_MISSING_RESOURCE_ERROR if the version was not found.

Stable:: ICU 4.2

◆ ulocdata_getDelimiter()

U_CAPI int32_t ulocdata_getDelimiter	(	ULocaleData *	uld,
		ULocaleDataDelimiterType	type,
		UChar *	result,
		int32_t	resultLength,
		UErrorCode *	status
	)

Returns one of the delimiter strings associated with a locale.

Parameters

uld	Pointer to the locale data object from which the delimiter string is to be retrieved.
type	the type of delimiter to be retrieved.
result	A pointer to a buffer to receive the result.
resultLength	The maximum size of result.
status	Pointer to an error code value

Returns: int32_t The total buffer size needed; if greater than resultLength, the output was truncated.

Stable:: ICU 3.4

◆ ulocdata_getExemplarSet()

U_CAPI USet * ulocdata_getExemplarSet	(	ULocaleData *	uld,
		USet *	fillIn,
		uint32_t	options,
		ULocaleDataExemplarSetType	extype,
		UErrorCode *	status
	)

Returns the set of exemplar characters for a locale.

Parameters

uld	Pointer to the locale data object from which the exemplar character set is to be retrieved.
fillIn	Pointer to a USet object to receive the exemplar character set for the given locale. Previous contents of fillIn are lost. If fillIn is NULL, then a new USet is created and returned. The caller owns the result and must dispose of it by calling uset_close.
options	Bitmask for options to apply to the exemplar pattern. Specify zero to retrieve the exemplar set as it is defined in the locale data. Specify USET_CASE_INSENSITIVE to retrieve a case-folded exemplar set. See uset_applyPattern for a complete list of valid options. The USET_IGNORE_SPACE bit is always set, regardless of the value of 'options'.
extype	Specifies the type of exemplar set to be retrieved.
status	Pointer to an input-output error code value; must not be NULL. Will be set to U_MISSING_RESOURCE_ERROR if the requested data is not available.

Returns: USet* Either fillIn, or if fillIn is NULL, a pointer to a newly-allocated USet that the user must close. In case of error, NULL is returned.

Stable:: ICU 3.4

◆ ulocdata_getLocaleDisplayPattern()

U_CAPI int32_t ulocdata_getLocaleDisplayPattern	(	ULocaleData *	uld,
		UChar *	pattern,
		int32_t	patternCapacity,
		UErrorCode *	status
	)

Returns locale display pattern associated with a locale.

Parameters

uld	Pointer to the locale data object from which the exemplar character set is to be retrieved.
pattern	locale display pattern for locale.
patternCapacity	the size of the buffer to store the locale display pattern with.
status	Must be a valid pointer to an error code value, which must not indicate a failure before the function call.

Returns: the actual buffer size needed for localeDisplayPattern. If it's greater than patternCapacity, the returned pattern will be truncated.

Stable:: ICU 4.2

◆ ulocdata_getLocaleSeparator()

U_CAPI int32_t ulocdata_getLocaleSeparator	(	ULocaleData *	uld,
		UChar *	separator,
		int32_t	separatorCapacity,
		UErrorCode *	status
	)

Returns locale separator associated with a locale.

Parameters

uld	Pointer to the locale data object from which the exemplar character set is to be retrieved.
separator	locale separator for locale.
separatorCapacity	the size of the buffer to store the locale separator with.
status	Must be a valid pointer to an error code value, which must not indicate a failure before the function call.

Returns: the actual buffer size needed for localeSeparator. If it's greater than separatorCapacity, the returned separator will be truncated.

Stable:: ICU 4.2

◆ ulocdata_getMeasurementSystem()

U_CAPI UMeasurementSystem ulocdata_getMeasurementSystem	(	const char *	localeID,
		UErrorCode *	status
	)

Returns the measurement system used in the locale specified by the localeID.

Please note that this API will change in ICU 3.6 and will use an ulocdata object.

Parameters

localeID	The id of the locale for which the measurement system to be retrieved.
status	Must be a valid pointer to an error code value, which must not indicate a failure before the function call.

Returns: UMeasurementSystem the measurement system used in the locale.

Stable:: ICU 2.8

◆ ulocdata_getNoSubstitute()

U_CAPI UBool ulocdata_getNoSubstitute ( ULocaleData * uld )

Retrieves the current "no Substitute" value of the locale data object.

If true, then any methods associated with the locale data object will return null when there is no data available for that method, given the locale ID supplied to ulocdata_open().

Parameters

uld	Pointer to the The locale data object to set.

Returns: UBool Value of the "no substitute" attribute.

Stable:: ICU 3.4

◆ ulocdata_getPaperSize()

U_CAPI void ulocdata_getPaperSize	(	const char *	localeID,
		int32_t *	height,
		int32_t *	width,
		UErrorCode *	status
	)

Returns the element gives the normal business letter size, and customary units.

The units for the numbers are always in milli-meters. For US since 8.5 and 11 do not yield an integral value when converted to milli-meters, the values are rounded off. So for A4 size paper the height and width are 297 mm and 210 mm respectively, and for US letter size the height and width are 279 mm and 216 mm respectively. Please note that this API will change in ICU 3.6 and will use an ulocdata object.

Parameters

localeID	The id of the locale for which the paper size information to be retrieved.
height	A pointer to int to receive the height information.
width	A pointer to int to receive the width information.
status	Must be a valid pointer to an error code value, which must not indicate a failure before the function call.

Stable:: ICU 2.8

◆ ulocdata_open()

U_CAPI ULocaleData * ulocdata_open	(	const char *	localeID,
		UErrorCode *	status
	)

Opens a locale data object for the given locale.

Parameters

localeID	Specifies the locale associated with this locale data object.
status	Pointer to error status code.

Stable:: ICU 3.4

◆ ulocdata_setNoSubstitute()

U_CAPI void ulocdata_setNoSubstitute	(	ULocaleData *	uld,
		UBool	setting
	)

Sets the "no Substitute" attribute of the locale data object.

If true, then any methods associated with the locale data object will return null when there is no data available for that method, given the locale ID supplied to ulocdata_open().

Parameters

uld	The locale data object to set.
setting	Value of the "no substitute" attribute.
