This rule finds calls to socket where there is no corresponding close call in the program analyzed. Leaving descriptors open will cause a resource leak that will persist even after the program terminates.

Ensure that all socket descriptors allocated by the program are freed before it terminates.

In the example below, the sockfd socket remains open when the main program finishes. The code should be updated to ensure that the socket is always closed when the program terminates.

SEI CERT C++ Coding Standard: ERR57-CPP. Do not leak resources when handling exceptions.
