Not at all. It doesn't take anything particular into "account", it just tells
you the size of the data and it uses the same argument set that fwrite()
offers which is why it uses two arguments to specify the size.

libcurl delivers binary data and it has no idea about what it delivers so it
cannot make any such distinction.
