Extending HCL OneDB™Beyond standard relational database objects, HCL OneDB™ can be extended to handle specialized data types, access methods, routines, and other objects. HCL OneDB™ includes many built-in extensions that are fully integrated in the database server. HCL OneDB™ also provides DataBlade® modules, which are packages of extended database objects for a particular purpose and that are installed separately from the database server. Alternatively, you can create your own user-defined objects for HCL OneDB™.
Creating extensionsYou can create user-defined data types, routines, access methods, and other database objects to suit your needs. You can use application programming interfaces to write user-defined routines and applications that access data in HCL OneDB™ databases.
DataBlade® API Function ReferenceThe HCL OneDB™ DataBlade® API Function Reference describes the DataBlade® API functions and the subset of functions that the DataBlade® API supports.
Function descriptionsThis section gives comprehensive reference information about the functions that are valid within DataBlade® API modules. It lists the function descriptions in alphabetical order, with syntax, usage information, and return values for the functions.
The rdownshift() functionThe rdownshift() function changes all the uppercase characters within a null-terminated string to lowercase characters.

The rdownshift() function

The rdownshift() function changes all the uppercase characters within a null-terminated string to lowercase characters.

Syntax

void rdownshift(s)
   char *s;

s: A pointer to a null-terminated string.

Usage

The rdownshift() function refers to the current locale to determine uppercase and lowercase letters. For the default locale, U.S. English, rdownshift() uses the ASCII lowercase (a to z) and uppercase (A to Z) letters.

If you use a nondefault locale, rdownshift() uses the lowercase and uppercase letters that the locale defines. For more information, see the HCL OneDB™ GLS User's Guide.
