int
mysql_session_track_get_next(MYSQL *mysql,
                             enum enum_session_state_type type,
                             const char **data,
                             size_t *length)

Description

This function fetches additional session state-change information received from the server, following that retrieved by mysql_session_track_get_first(). The parameters for mysql_session_track_get_next() are the same as for mysql_session_track_get_first().

Following a successful call to mysql_session_track_get_first(), call mysql_session_track_get_next() repeatedly until it returns nonzero to indicate no more information is available. The calling sequence for mysql_session_track_get_next() is similar to that for mysql_session_track_get_first(). For more information and an example that demonstrates both functions, see Section 5.4.71, “mysql_session_track_get_first()”.

Zero for success. Nonzero if an error occurred.
