extern "C" a_sql_uint32 ( SQL_CALLBACK *entry-point-function )( a_init_term_breaker *data  );

1 on error and 0 on successful execution

This function must be implemented in the external term breaker library, and needs to be re-entrant as it can be executed on multiple threads simultaneously.

The caller of the function provides a pointer to an a_text_source object that will serve as the producer for the term breaker. The caller should also provide the character set of the input.

This function provides to the caller a pointer to an external term breaker (a_word_source structure) and the supported character set.

If desired_charset and actual_charset are not the same, the database server converts the term breaker input to the character set specified by actual_charset.

Note that character set conversion can cause a degradation in performance.
