const USER_CONN uc 
)

◆ check_mqh()

uint  check_command 
)

◆ close_connection()

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

Close a connection.

Parameters
thdThread handle.
sql_errnoThe error code to send before disconnect.
server_shutdownTrue for a server shutdown
generate_eventGenerate 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
thdthread handle

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