Counter this with a quote from the man page for CURLOPT_READFUNCTION:
"The data area pointed at by the pointer buffer should be filled up with at
most size multiplied with nmemb number of bytes by your function."
size multiplied with nmemb. You copy just 'size' bytes, which happens to be 1
as a fixed value here, so you copy one byte at a time.
