Description

Note

As of MySQL 5.7.11, mysql_list_processes() is deprecated and is subject to removal in a future version of MySQL. Instead, use mysql_real_query() or mysql_query() to execute a SHOW PROCESSLIST statement.

Returns a result set describing the current server threads. This is the same kind of information as that reported by mysqladmin processlist or a SHOW PROCESSLIST query.

You must free the result set with mysql_free_result().
