libdvbpsi | branch: master | Jean-Paul Saman <[email protected]> | Fri Apr 11 15:20:53 2014 +0200| [f70707bbd022f88a12cacf83b57dcdf07c6dd57a] | committer: Jean-Paul Saman

examples/dvbinfo/tcp.c: Resource leak (CID 17269)

The code does not leak a socket descriptor while looping over addrinfo pointer structs.However initializing s_ctl to -1 again after calling close(s_ctl) is good practise.
