These constants identify classes of events that can be monitored using the sqlite3_trace_v2() tracing logic. The third argument to sqlite3_trace_v2() is an OR-ed combination of one or more of the following constants. The first argument to the trace callback is one of the following constants.

New tracing constants may be added in future releases.

A trace callback has four arguments: xCallback(T,C,P,X). The T argument is one of the integer type codes above. The C argument is a copy of the context pointer passed in as the fourth argument to sqlite3_trace_v2(). The P and X arguments are pointers whose meanings depend on T.
