How can I change the socket priority by using
int setsockopt(int sockfd, int level, int optname,const void *optval, socklen_t optlen);
and also help me to understand what is the use of const void *optval.

I read that also their he mentiond int optval=7 // valid values are in the range [1,7] // 1- low priority, 7 - high priority // but low number gets high priority right..? – Bala Apr 06 '18 at 06:14
