The data passed to this function is not null-terminated.
The callback function is passed as much data as possible in all invokes, but
you must not make any assumptions. It may be one byte, it may be
thousands. The maximum amount of body data that is passed to the write
callback is defined in the curl.h header file: *CURL_MAX_WRITE_SIZE* (the
usual default is 16K). If CURLOPT_HEADER(3) is enabled, which makes header
data get passed to the write callback, you can get up to
*CURL_MAX_HTTP_HEADER* bytes of header data passed into it. This usually means
100K.
