Do I need to wrap SQlite calls with extern "C" in my C++ application?

DO I need to wrap SQLite(http://www.sqlite.org/) library calls in my C++ application as :

extern "C" {    

    //Wrapping SQLite C header
    #include "sqlite3.h" 

    // Some example function definitions
    int sqlite3_open(const char *filename,sqlite3 **ppDb);
    void sqlite3_free(void*);
    int sqlite3_close(sqlite3*);
}

Or can I access the library directly (as most examples show in the website)? Would also love to know the reason behind the right answer.

sqlite3.h already includes an extern "C" wrapper. From the source:

/*
** Make sure we can call this stuff from C++.
*/
#ifdef __cplusplus
extern "C" {
#endif

…

#ifdef __cplusplus
}  /* end of the 'extern "C"' block */
#endif

As such, you don't need to wrap it yourself.
