Description

int php_getdns_context_get_limit_outstanding_queries ( int $context , int &$value )

value: An integer value between 0 and 65535 inclusive that represents the upper limit on the number of outstanding DNS queries. A value of 0 (zero) indicates that no limit is set. Note that this argument is passed by reference and any existing value will be overwritten.

Return Values
