Manual Reference Pages - CURLOPT_BUFFERSIZE (3)
CURLOPT_BUFFERSIZE - set preferred receive buffer size
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_BUFFERSIZE, long size);
Pass a long specifying your preferred size (in bytes) for the receive
buffer in libcurl. The main point of this would be that the write callback
gets called more often and with smaller chunks. This is just treated as a
request, not an order. You cannot be guaranteed to actually get the given
This size is by default set as big as possible (CURL_MAX_WRITE_SIZE), so
it only makes sense to use this option if you want it smaller.
Added in 7.10
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
