National Language Support-related APIs

The national language support-related APIs work with the national language support (NLS) functions.

The NLS-related APIs that work with UCS2 (Universal Multiple-Octet Coded Character Set with 16 bits per character) character sets are:

• Advance to Next Composite Character Sequence (UniNextCompChar()) API
• Composite Character Sequence Code Element Count (UniQueryCompCharLen()) API
• Convert Case (QLGCNVCS, QlgConvertCase) API
• Number of Composite Character Sequences (UniQueryCompChar()) API
• Retrieve Locale Information (QLGRTVLC, QlgRetrieveLocaleInformation) API
• Transform UCS Data (QlgTransformUCSData()) API

The NLS-related APIs are:

• Advance to Next Composite Character Sequence (UniNextCompChar()) locates the next non-combining character in a string.
• Composite Character Sequence Code Element Count (UniQueryCompCharLen()) computes the number of code elements in a composite character sequence.
• Convert Case (QLGCNVCS, QlgConvertCase) provides case conversion to either uppercase or lowercase.
• Convert Sort Sequence Table (QLGCNVSS) converts a sort sequence table from one coded character set identifier (CCSID) to another.
• Convert Text Descriptor (QlgCvtTextDescToDesc) converts a descriptor of text from one type (CCSID, for example) to another type (IANA name, for example).
• Number of Composite Character Sequences (UniQueryCompChar()) computes the number of composite character sequences in a code element array.
• Retrieve CCSID Data (QLGRTVCD) retrieves different subsets of CCSIDs based on the selection type.
• Retrieve CCSID Text (QLGRTVCT) retrieves different subsets of CCSIDs' values and their descriptions, if available.
• Retrieve Country or Region Identifiers (QLGRTVCI) retrieves a list of country or region identifiers and their descriptions.
• Retrieve Default CCSID (QLGRTVDC) retrieves the default CCSID given a language ID.
• Retrieve Language IDs (QLGRTVLI) retrieves a list of language identifiers.
• Retrieve Language Information (QLGRLNGI) returns a selected national language version (NLV) based on the specified product, option, and language identifier.
• Retrieve Locale Information (QLGRTVLC, QlgRetrieveLocaleInformation) retrieves one or all categories of a locale.
• Retrieve Sort Sequence Table (QLGRTVSS) retrieves a specified sort sequence table.
• Scan String for Mixed Data (QLGSCNMX) tests a mixed input string for double-byte characters.
• Sort (QLGSORT) provides a generalized sort function.
• Sort Input/Output (QLGSRTIO) provides a set of records to be sorted or returns a set of records that have already been sorted.
• Transform UCS Data (QlgTransformUCSData()) transforms, through a formula as compared to a mapping, data from one form of Unicode to another.
• Truncate Character Data (QLGTRDTA) truncates a CCSID-tagged string of character data to a specified length.
• Validate CCSID (QtqValidateCCSID()) determines whether the specified CCSID is supported by the system.
• Validate Language ID (QLGVLID) ensures that a language identifier is supported.
