NAME
CURLOPT_BUFFERSIZE - set preferred receive buffer size
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_BUFFERSIZE, long size);
DESCRIPTION
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. Secondly, for
some protocols, there's a benefit of having a larger buffer for perfor-
mance.
This is just treated as a request, not an order. You cannot be guaran-
teed to actually get the given size.
This buffer size is by default CURL_MAX_WRITE_SIZE (16kB). The maximum
buffer size allowed to set is CURL_MAX_READ_SIZE (512kB).
DEFAULT
CURL_MAX_WRITE_SIZE(16kB)
PROTOCOLS
All
EXAMPLE
TODO
AVAILABILITY
Added in 7.10. Growing the buffer was added in 7.53.0.
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION
if not.
