The prototype for setsockopt is:
int setsockopt(int socket, int level, int option_name, const void *option_value, socklen_t option_len);
Are the following all correct ? Which are not ?
a.) int buffsize = 50000; setsockopt(s, SOL_SOCKET, SO_RCVBUF, (char *)&buffsize, sizeof(buffsize));
b.) int buffsize = 50000; setsockopt(s, SOL_SOCKET, SO_RCVBUF, (void *)&buffsize, sizeof(buffsize));
c.) char *buffsize = "50000"; setsockopt(s, SOL_SOCKET, SO_RCVBUF, buffsize, strlen(buffsize));
d.) setsockopt(s, SOL_SOCKET, SO_RCVBUF, "50000", 5);
