/*!
* \brief Builds a property list for pszDriver.
*
* Adds common DSN properties (Name,Driver,Description) and then asks the
* drivers setup to load any additional properties.
*
* This is used to support editing DSN properties without forcing the driver
* developer to create a UI for the many different UI implementations. The
* driver developer can just implement ODBCINSTGetProperties. This function
* can then call ODBCINSTGetProperties to get properties. The code that calls
* this function can then display the properties in the UI in use.
*
* \param pszDriver Friendly driver name.
* \param hFirstProperty Place to store the properties list. The properties (including
* some of the elements within each HODBCINSTPROPERTY may
* need to be freed using \sa ODBCINSTDestructProperties.
*
* \return int
* \retval ODBCINST_ERROR Called failed. No memory was allocated at hFirstProperty. The
* likely reasons for this; \li failed to lookup setup library name
* \li failed to load setup library \li failed to find
* ODBCINSTGetProperties symbol in setup library
* \retval ODBCINST_SUCCESS Success! Do not forget to call ODBCINSTDestructProperties to
* free memory used by the properties when you are done.
*
* \sa ODBCINSTDestructProperties
