#includeIn this example, we create a socket using `socket()` from the `sys/socket.h` library. We then do some operations with the socket and close it using `RTest::Close(sockfd)` to ensure that any remaining data is sent and that the socket is properly closed. Package library: Based on the use of the `RTest` namespace, it seems likely that these code examples are part of a testing framework/library for C++ called "RTest". Without further information, it is difficult to determine if this is a widely-used package or a custom library.#include int main() { int sockfd = socket(AF_INET, SOCK_STREAM, 0); if (sockfd == -1) { RTest::Fail("Failed to create socket"); } // do something with the socket RTest::Close(sockfd); return RTest::Summary(); }
