# Setup DLL API Reference
This section describes the syntax of the driver setup DLL API,which consists of two functions (**ConfigDriver** and **ConfigDSN**). **ConfigDriver** and **ConfigDSN** can be either in the driver DLL or in a separate setup DLL.  
  
 In addition, this section describes the syntax of the translator setup DLL API, which consists of a single function (**ConfigTranslator**). **ConfigTranslator** can be either in the translator DLL or in a separate setup DLL.  
  
 Each function is labeled with the version of ODBC in which it was introduced.
