Is this code Endian safe?

Question

I am testing following peace of code for possible Endian issue. Code was written for ppc and needs to be run on x86 box now.

string Mac = nodeMessage->getMac();
char mac_string[17];
strncpy(mac_string, Mac.c_str(),16);

What is the issue you are facing? – Subhajit Jul 30 '15 at 06:22 — Subhajit, Jul 30 '15 at 06:22

Endian-ness of a machine affects integral values that are more than one byte wide. I don't see any integral values there. Hence, I don't see any Endian-ness problems associated with the above code.

If you are dealing only with 1 byte chars(ASCII) then its Endian safe else its not.

the following link may be helpful.

Completing the answer of R Sahu, the problem could be the nodeMessage and how it manages the mac (I suppose that it refers to a mac address).
