The context in which an SQL function executes is stored in an

sqlite3_context object. A pointer to an sqlite3_context object

is always first parameter to <a href="../appfunc.html">application-defined SQL functions</a>.

The application-defined SQL function implementation will pass this
|
|
pointer through into calls to <a href="../c3ref/result_blob.html">sqlite3_result()</a>,
