Sorry i'm a little late to the party.

No, fread doesn't handle this for you. It must be done manually. Luckily its not hard. I like to use fread()'s return to set the NUL like so:

char buffer[16+1]; /*leaving room for '\0' */
x = fread(buffer, sizeof(char), 16, stream);
buffer[x]='\0';

and now you have yourself a \0 terminated string, and as a bonus, we have a nifty variable x, which actually saves us the trouble of running strlen() if we ever needed it later. neat!
