You are right. It is documented:
========================================
/* from http://curl.haxx.se/libcurl/c/curl_easy_setopt.html#CURLOPTREADFUNCTION */
If you set the callback pointer to NULL, or don't set it at all, the default internal read function will be used. It is simply doing an fread() on the FILE * stream set with CURLOPT_READDATA.
========================================
