Name

mariadb_cancel - Immediately aborts a connection

Synopsis

#include <mysql.h>
int mariadb_cancel(MYSQL * mysql);

Description

To free the memory, mysql_close(3) must be called. mariadb_cancel() is useful to break long queries in situations where sending KILL is not possible.

Parameter

mysql - mysql handle, which was previously allocated by mysql_init(3) and connected by mysql_real_connect(3).

Return value

Returns zero on success or a non-zero value on error.
