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 ldchar() functionThe ldchar() function copies a fixed-length string into a null-terminated string and removes any trailing blanks.

The ldchar() function

The ldchar() function copies a fixed-length string into a null-terminated string and removes any trailing blanks.

Syntax

void ldchar(from, count, to)
   char *from;
   mint count;
   char *to;

from: A pointer to the fixed-length source string.
count: The number of bytes in the fixed-length source string.
to: A pointer to the first byte of a null-terminated destination string. The to argument can point to the same location as the from argument or to a location that overlaps the from argument. If this is the case, ldchar() does not preserve the value to which from points.
