Hi,
currently most of the applications that must take care of endianess use ntohl/htonl ntohs/htons functions. When the size of the integer change we need to change between the -s and -l functions (or maybe remove the call for chars).

Why are they template ? Atfer all, the 3 overload is fully sufficent I think
Oups! You are right.
A template would make it harder to accidentally do an implicit conversion of an unsupported argument type before it is byte swapped. Hi, you are right, and I think that we don't need accidental implicit conversions. I have tested with and withou the template and there is a conclict without.
