check_for_max_user_connections()

int check_for_max_user_connections	(	THD *	thd,
		const USER_CONN *	uc
	)

check_mqh()

bool check_mqh	(	THD *	thd,
		uint	check_command
	)

close_connection()

void close_connection	(	THD *	thd,
		uint	sql_errno,
		bool	server_shutdown,
		bool	generate_event
	)

Close a connection.

Parameters

thd	Thread handle.
sql_errno	The error code to send before disconnect.
server_shutdown	True for a server shutdown
generate_event	Generate Audit API disconnect event.

Note

For the connection that is doing shutdown, this is called twice

Set thread character set variables from the given ID.

Parameters

thd	thread handle
cs_number	character set and collation ID

Return values

0	OK; character_set_client, collation_connection and character_set_results are set to the new value, or to the default global values.
1	error, e.g. the given ID is not supported by parser. Corresponding SQL error is sent.
