48335640Shselasky * However there is no guarantees that the string will be zero-terminated.
49335640Shselasky * Best practice is to define the errbuf variable as a char of size 'PCAP_ERRBUF_SIZE+1'
50335640Shselasky * and to insert manually the termination char at the end of the buffer. This will
51335640Shselasky * guarantee that no buffer overflows occur even if we use the printf() to show
