mysql_kill - Kills a connection


#include <mysql.h>

int mysql_kill(MYSQL * mysql,
               unsigned long);


This function is used to ask the server to kill a MariaDB thread specified by the processid parameter. This value must be retrieved by [show-processlist()](SHOW PROCESSLIST]]. If trying to kill the own connection mysql_thread_id(3) should be used.


  • mysql - a connection identifier, which was previously allocated by mysql_init(3) and connected by mysql_real_connect(3). Returns 0 on success, otherwise nonzero.
  • long - process id


  • To stop a running command without killing the connection use KILL QUERY.
  • The mysql_kill() function only kills a connection, it doesn’t free any memory - this must be done explicitly by calling mysql_close(3).

Return value

Returns zero on success, non zero on error.
