* \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.
