46 * \warning All the RPCAP functions that are allowed to return a buffer containing
47 * the error description can return max PCAP_ERRBUF_SIZE characters.
48 * However there is no guarantees that the string will be zero-terminated.
49 * Best practice is to define the errbuf variable as a char of size 'PCAP_ERRBUF_SIZE+1'
50 * and to insert manually the termination char at the end of the buffer. This will
51 * guarantee that no buffer overflows occur even if we use the printf() to show
52 * the error on the screen.
