ExpValidateNlsLocaleData()

static __inline BOOLEAN ExpValidateNlsLocaleData ( _In_ PKEY_VALUE_PARTIAL_INFORMATION  LocaleData )

static

Validates the registry data of a NLS locale.

Parameters

[in]

LocaleData

A pointer to partial information that contains the NLS locale data.

Returns

Returns TRUE if the following conditions are met, otherwise FALSE is returned.

ExpValidateNlsLocaleId()

static NTSTATUS ExpValidateNlsLocaleId ( _In_ LCID  LocaleId )

static

Validates a NLS locale. Whether a locale is valid or not depends on the following conditions:

• The locale must exist in the Locale key, otherwise in the Alternate Sorts key;
• The locale must exist in the Language Groups key, and the queried value must be readable;
• The locale registry data must be of REG_SIZE type, has a consistent length and the locale belongs to a supported language group that is set.

Parameters

[in]

LocaleId

A locale identifier that corresponds to a specific locale to be validated.

Returns

Returns STATUS_SUCCESS if the function has successfully validated the locale and it is valid. STATUS_OBJECT_NAME_NOT_FOUND is returned if the following locale does not exist on the system. A failure NTSTATUS code is returned otherwise.
