It usesMYSQL_BIND structures to supply the data.bind is the address of an array ofMYSQL_BIND structures. The client library expects the array to contain one element for each? parameter marker that is present in the query.

Suppose that you prepare the following statement:

INSERT INTO mytbl VALUES(?,?,?)

When you bind the parameters, the array ofMYSQL_BIND structures must contain three elements, and can be declared like this:

MYSQL_BIND bind[3];
