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 ifx_int8toasc() functionThe ifx_int8toasc() function converts an int8 type number to a C char type value.

The ifx_int8toasc() function

The ifx_int8toasc() function converts an int8 type number to a C char type value.

Syntax

mint ifx_int8toasc(int8_val, strng_val, len)
   ifx_int8_t *int8_val;
   char *strng_val;
   int len;

int8_val: A pointer to the int8 structure that contains the value to convert to a text string.
strn_val: A pointer to the first byte of the character buffer to contain the text string.
len: The size of strng_val, in bytes, minus 1 for the null terminator.

Usage

If the int8 number does not fit into a character string of length len, ifx_int8toasc() converts the number to an exponential notation. If the number still does not fit, ifx_int8toasc() fills the string with asterisks. If the number is shorter than the string, ifx_int8toasc() left justifies the number and pads it on the right with blanks.

Because the character string that ifx_int8toasc() returns is not null terminated, your program must add a null character to the string before you print it.

When you use a nondefault locale (one other than U.S. English), ifx_int8toasc() supports non-ASCII characters in the strng_val character string. For more information, see the HCL OneDB™ GLS User's Guide.

Return values

0: The conversion was successful.
-1207: The converted value does not fit into the allocated space.
