◆ has_invalid_udf_int_args()

static bool has_invalid_udf_int_args	(	UDF_ARGS *	args,
		unsigned int	arg_count
	)

static

Validate that a UDF argument list contains the expected number of integer-valued arguments and that each argument has a non-null value pointer.

This guards UDFs against typed SQL NULL inputs such as CAST(NULL AS SIGNED), which may report INT_RESULT in args->arg_type[] while still providing a null entry in args->args[].

Parameters

args	UDF argument descriptor supplied by the server.
arg_count	Expected number of integer arguments.

Return values

true	The argument list is invalid.
false	The argument list is valid.

◆ page_track_callback()

int page_track_callback	(	MYSQL_THD	opaque_thd,
		const uchar *	buffer,
		size_t	buffer_length,
		int	page_count,
		void *	context
	)

Callback method from InnoDB page-tracking to return the changed pages.

Parameters

[in]	opaque_thd	Current thread context.
[in]	buffer	Buffer filled with 8 byte page ids.
[in]	buffer_length	Total buffer length
[in]	page_count	Number of pages in the buffer
[in]	context	User data pointer passed to the InnoDB service

Returns: Status if the call-back was successful in handling the data

Return values

0	success
non-zero	failure
