Detailed Description
Endianness conversion functions for Network data.
Converts values between the local system and big-endian network data (e.g. IP, Ethernet, but NOT WLAN).
The host term in the descriptions of these functions refers to the local system, i.e. application or embedded system. Therefore, these functions will behave differently depending on which side they are used. The reason of this terminology is to keep the same name than the standard C function.
Behavior will depends on the endianness of the host:
- little endian: swap bytes;
- big endian: identity function.
