[unixODBC-dev] SQLDriverConnectW() returns an error !

Thanks for the input, Nick!
That was helpful indeed! I wondered if this is documented anywhere.
As I am getting bus error for wcslen(), I presume the driver is expecting 4
byte Unicode.
If I compile unixODBC with SQL_WCHART_CONVERT defined, I wonder mapping of
char to wchar which you mentioned in the earlier mail will not do the task.
What conversion method should be used in that case so as to provide
appropriate SQLWCHAR data to SQLDriverConnectW function ?

Thanks very much.

It may be that the driver (you didn't say which one) is expecting 4 byte 
unicode. in which case recompile unixODBC with SQL_WCHART_CONVERT defined.
