my_bool mysql_commit(MYSQL *mysql)
Commits the current transaction.
As of MySQL 5.0.3, the action of this function is subject to the
value of the
system variable. In particular, if the value of
completion_type is 2, the
server performs a release after terminating a transaction and
closes the client connection. The client program should call
mysql_close() to close the
connection from the client side.
Zero for success. Nonzero if an error occurred.
