Web22 dec. 2024 · In your code, you don't need to call htonl on rec_addr, because that value was returned by inet_addr, and that function returns the address in network byte order. You do however need to call htons on rec_port. Solution 3 "Network byte order" always means big endian. "Host byte order" depends on architecture of host. Webhtons (), htonl () , , ntohl () Convert multi-byte integer types from host byte order to network byte order. Prototypes. #include . uint32_t htonl (uint32_t hostlong); …

First you need to know (or determine) the byte order of the file data. Then only if that is different from the host byte order do you do any endianess corrections. shishas murcia
