[sqlite] Question on sqlite3_transfer_bindings()

[Eugene Wee]

Hi,
This concerns SQLite3.2

I noticed that there's a function in the C API:
int sqlite3_transfer_bindings(sqlite3_stmt*, sqlite3_stmt*);
How does one use it?
A comment in vdbeapi.c notes that "If the two statements contain a different 
number of bindings, then an SQLITE_ERROR is returned."
Unfortunately, the implementation of the function is rather opaque to me at this 
point, so I really have no idea how to use it, and would like to find out.

Thanks,
Eugene Wee
