 * \warning All the RPCAP functions that are allowed to return a buffer containing

 * the error description can return max PCAP_ERRBUF_SIZE characters.

 * However there is no guarantees that the string will be zero-terminated.

 * Best practice is to define the errbuf variable as a char of size 'PCAP_ERRBUF_SIZE+1'

 * and to insert manually the termination char at the end of the buffer. This will

 * guarantee that no buffer overflows occur even if we use the printf() to show

 * the error on the screen.
