mi_string* mi_tab_owner(MI_AM_TABLE_DESC *tableDesc)

tableDesc

points to the table descriptor.

The user who creates a table owns that table. The database server identifies the owner by user ID, which it stores in the systables system catalog table. In some environments, user ID of the table owner must precede the table name as follows:

SELECT * from owner.table_name

The string contains the user ID of the table owner.

See the description of the Owner Name segment in the IBM Informix: Guide to SQL Syntax.
