c-ares is a C library that provides asynchronous DNS resolution capabilities. It is designed to be lightweight and portable, and is commonly used in network applications that need to perform DNS lookups without blocking.
The c-ares library provides an event-driven interface that allows applications to initiate DNS requests and receive responses asynchronously. This means that applications can continue to execute other tasks while waiting for DNS responses, instead of blocking until the response is received.
The library supports both IPv4 and IPv6 address resolution, as well as other DNS record types such as MX, SRV, and TXT. It also includes support for DNSSEC validation, which can help to prevent DNS cache poisoning attacks.
One of the key features of c-ares is its support for multiple DNS queries in parallel. This allows applications to initiate multiple DNS requests at the same time, and then process the responses as they are received. This can greatly improve the efficiency of DNS lookups, especially in applications that need to perform many DNS requests.
c-ares also includes support for various network event notification mechanisms, such as select(), poll(), and epoll(). This allows applications to integrate c-ares with their event loop, and receive notifications when DNS responses are ready.
Overall, c-ares is a useful library for network applications that need to perform asynchronous DNS lookups. Its lightweight and portable design, along with its support for multiple DNS queries in parallel, make it a popular choice for many developers.
