DNSDiscardName Function

static void DNSDiscardName();

This function reads a name string from the DNS socket. Each string consists of a series of labels. Each label consists of a length prefix byte, followed by the label bytes. At the end of the string, a zero length label is found as termination. If name compression is used, this function will automatically detect the pointer and discard it.
