rs_get_textptr

Retrieves the description for a text, unitext, or image column.

Examples

Example 1 – Creates an rs_get_textptr function string for the repcopy column in the blurbs table. The function string name, copy, is the name of the text, unitext, or image column in the replication definition.
```
create function string
 blurbs_rep.rs_get_textptr;copy
 for sqlserver2_function_class
 output language
 'select repcopy from blurbs
 where au_id = ?au_id!new?'
```

Replication Server calls rs_get_textptr to retrieve a text, unitext, or image column description before it sends data with the Client-Library function ct_send_data.
rs_get_textptr has replication definition scope.
When you create a replication definition, Replication Server generates an rs_get_textptr function string for the rs_sqlserver_function_class and rs_default_function_class classes for each replicated text, unitext, or image column in the replication definition.
If you use a user-created base function-string class, you must create an rs_get_textptr function string for each replicated text, unitext, or image column included in the replication definition.
Create or customize an rs_get_textptr function string at the Replication Server where you created the replication definition.
rs_get_textptr must return a text or unitext column description for a text, unitext, or image column in a specified row. The text or unitext column description must conform to Open Server requirements for returning an “I/O descriptor structure.” For information about this structure, refer to the Open Server Server-Library/C Reference Manual.
