Detailed Description

C API: Resource Bundle.

C API: Resource Bundle

C API representing a collection of resource information pertaining to a given locale. A resource bundle provides a way of accessing locale- specific information in a data file. You create a resource bundle that manages the resources for a given locale and then ask it for individual resources.

Resource bundles in ICU4C are currently defined using text files which conform to the following BNF definition. More on resource bundle concepts and syntax can be found in the Users Guide.

const char* ures_getUTF8String ( const UResourceBundle resB,
char *  dest,
int32_t *  length,
UBool  forceCopy,
UErrorCode status 
)

Returns a UTF-8 string from a string resource.

The UTF-8 string may be returnable directly as a pointer, or it may need to be copied, or transformed from UTF-16 using u_strToUTF8() or equivalent.

If forceCopy==TRUE, then the string is always written to the dest buffer and dest is returned.

If forceCopy==FALSE, then the string is returned as a pointer if possible, without needing a dest buffer (it can be NULL). If the string needs to be copied or transformed, then it may be placed into dest at an arbitrary offset.

If the string is to be written to dest, then U_BUFFER_OVERFLOW_ERROR and U_STRING_NOT_TERMINATED_WARNING are set if appropriate, as usual.

If the string is transformed from UTF-16, then a conversion error may occur if an unpaired surrogate is encountered. If the function is successful, then the output UTF-8 string is always well-formed.

Parameters
resBResource bundle.
destDestination buffer. Can be NULL only if capacity=*length==0.
lengthInput: Capacity of destination buffer. Output: Actual length of the UTF-8 string, not counting the terminating NUL, even in case of U_BUFFER_OVERFLOW_ERROR. Can be NULL, meaning capacity=0 and the string length is not returned to the caller.
forceCopyIf TRUE, then the output string will always be written to dest, with U_BUFFER_OVERFLOW_ERROR and U_STRING_NOT_TERMINATED_WARNING set if appropriate. If FALSE, then the dest buffer may or may not contain a copy of the string. dest may or may not be modified. If a copy needs to be written, then the UErrorCode parameter indicates overflow etc. as usual.
statusPointer to a standard ICU error code. Its input value must pass the U_SUCCESS() test, or else the function returns immediately. Check for U_FAILURE() on output or use with function chaining. (See User Guide for details.)
Returns
The pointer to the UTF-8 string. It may be dest, or at some offset from dest (only if !forceCopy), or in unrelated memory. Always NUL-terminated unless the string was written to dest and length==capacity (in which case U_STRING_NOT_TERMINATED_WARNING is set).

Returns
A version number string as specified in the resource bundle or its parent. The caller does not own this string.

UResourceBundle* ures_open ( const char *  packageName,
const char *  locale,
UErrorCode status 
)

Opens a UResourceBundle, from which users can extract strings by using their corresponding keys.

Note that the caller is responsible of calling ures_close on each succesfully opened resource bundle.

Parameters
packageNameThe packageName and locale together point to an ICU udata object, as defined by udata_open( packageName, "res", locale, err) or equivalent. Typically, packageName will refer to a (.dat) file, or to a package registered with udata_setAppData(). Using a full file or directory pathname for packageName is deprecated. If NULL, ICU data will be used.
localespecifies the locale for which we want to open the resource if NULL, the default locale will be used. If strlen(locale) == 0 root locale will be used.
statusfills in the outgoing error code. The UErrorCode err parameter is used to return status information to the user. To check whether the construction succeeded or not, you should check the value of U_SUCCESS(err). If you wish more detailed information, you can check for informational status results which still indicate success. U_USING_FALLBACK_WARNING indicates that a fall back locale was used. For example, 'de_CH' was requested, but nothing was found there, so 'de' was used. U_USING_DEFAULT_WARNING indicates that the default locale data or root locale data was used; neither the requested locale nor any of its fall back locales could be found. Please see the users guide for more information on this topic.

UResourceBundle* ures_openDirect ( const char *  packageName,
const char *  locale,
UErrorCode status 
)

This function does not care what kind of localeID is passed in.

It simply opens a bundle with that name. Fallback mechanism is disabled for the new bundle. If the requested bundle contains an %ALIAS directive, the results are undefined.

Parameters
packageNameThe packageName and locale together point to an ICU udata object, as defined by udata_open( packageName, "res", locale, err) or equivalent. Typically, packageName will refer to a (.dat) file, or to a package registered with udata_setAppData(). Using a full file or directory pathname for packageName is deprecated. If NULL, ICU data will be used.
localespecifies the locale for which we want to open the resource if NULL, the default locale will be used. If strlen(locale) == 0 root locale will be used.
statusfills in the outgoing error code. Either U_ZERO_ERROR or U_MISSING_RESOURCE_ERROR
Returns
a newly allocated resource bundle or NULL if it doesn't exist.

void ures_openFillIn ( UResourceBundle r,
const char *  packageName,
const char *  localeID,
UErrorCode status 
)

Same as ures_open() but uses the fill-in parameter instead of allocating a bundle, if r!=NULL.

TODO need to revisit usefulness of this function and usage model for fillIn parameters without knowing sizeof(UResourceBundle)

Parameters
rThe resourcebundle to open
packageNameThe packageName and locale together point to an ICU udata object, as defined by udata_open( packageName, "res", locale, err) or equivalent. Typically, packageName will refer to a (.dat) file, or to a package registered with udata_setAppData(). Using a full file or directory pathname for packageName is deprecated. If NULL, ICU data will be used.
localeIDspecifies the locale for which we want to open the resource
statusThe error code
Returns
a newly allocated resource bundle or NULL if it doesn't exist.
Internal:
Do not use. This API is for internal use only.
UResourceBundle* ures_openU ( const UChar packageName,
const char *  locale,
UErrorCode status 
)

Same as ures_open() but takes a const UChar *path.

This path will be converted to char * using the default converter, then ures_open() is called.

Parameters
packageNameThe packageName and locale together point to an ICU udata object, as defined by udata_open( packageName, "res", locale, err) or equivalent. Typically, packageName will refer to a (.dat) file, or to a package registered with udata_setAppData(). Using a full file or directory pathname for packageName is deprecated. If NULL, ICU data will be used.
localespecifies the locale for which we want to open the resource if NULL, the default locale will be used. If strlen(locale) == 0 root locale will be used.
statusfills in the outgoing error code.
Returns
a newly allocated resource bundle.
