Detailed Description

Bounded-buffer sink state for a page fetch.

Handed to priv_mdl_net_curl_buf_write as libcurl's write-data. The write callback appends into buf until cap is reached, then latches overflow and aborts the transfer.

Invariant: len <= cap whenever overflow is false.

See also: priv_mdl_net_curl_buf_write()

Since: 0.1.0
