## SQLite C Interface

### Tracing And Profiling Functions

>     void *sqlite3_trace(sqlite3*, void(*xTrace)(void*,const char*), void*);
>     void *sqlite3_profile(sqlite3*,
>        void(*xProfile)(void*,const char*,sqlite3_uint64), void*);

These routines register callback functions that can be used for tracing and profiling the execution of SQL statements. The callback function registered by sqlite3_trace() is invoked at the first sqlite3_step() for the evaluation of an SQL statement. The callback function registered by sqlite3_profile() is invoked as each SQL statement finishes and includes information on how long that statement ran.

The sqlite3_profile() API is currently considered experimental and is subject to change.
