mariadb_cancel(3) MariaDB Connector/C mariadb_cancel(3)
Name mariadb_cancel - Immediately aborts a connection
Synopsis
#include <mysql.h>
int mariadb_cancel(MYSQL * mysql);

Description Immediately aborts a connection by making all subsequent read/write operations fail. mariadb_cancel() does not invalidate memory used for mysql structure, nor close any communication channels. 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.
History mariadb_cancel() was added in Connector/C 3.0
