The argument to the SQLITE_FCNTL_PRAGMA file control is an array of pointers to strings (char**) in which the second element of the array is the name of the pragma and the third element is the argument to the pragma or NULL if the pragma has no argument.

The handler for an SQLITE_FCNTL_PRAGMA file control can optionally make the first element of the char** argument point to a string obtained from sqlite3_mprintf() or the equivalent and that string will become the result of the pragma or the error message if the pragma fails.

If the SQLITE_FCNTL_PRAGMA file control returns SQLITE_OK, then the parser assumes that the VFS has handled the PRAGMA itself and the parser generates a no-op prepared statement if result string is NULL, or that returns a copy of the result string if the string is non-NULL.

If the SQLITE_FCNTL_PRAGMA file control returns any result code other than SQLITE_OK or SQLITE_NOTFOUND, that means that the VFS encountered an error while handling the PRAGMA and the compilation of the PRAGMA fails with an error.
