curldown is this new file format for libcurl man pages. It is markdown inspired with differences: - Each file has a set of leading headers with meta-data - Supports a small subset of markdown - Uses .md file extensions for editors/IDE/GitHub to treat them nicely - Generates man pages very similar to the previous ones - Generates man pages that still convert nicely to HTML on the website - Detects and highlights mentions of curl symbols automatically (when their man page section is specified) tools: - cd2nroff: converts from curldown to nroff man page - nroff2cd: convert an (old) nroff man page to curldown - cdall: convert many nroff pages to curldown versions - cd2cd: verifies and updates a curldown to latest curldown This setup generates .3 versions of all the curldown versions at build time. CI: Since the documentation is now technically markdown in the eyes of many things, the CI runs many more tests and checks on this documentation, including proselint, link checkers and tests that make sure we capitalize the first letter after a period... Closes #12730

# NAME
|
|
|
|
CURLOPT_MAXCONNECTS - maximum connection cache size
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXCONNECTS, long amount);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
Pass a long. The set *amount* is the maximum number of simultaneously open
|
|
persistent connections that libcurl may cache in the pool associated with this
|
|
handle. The default is 5, and there is not much point in changing this value
|
|
unless you are perfectly aware of how this works. This concerns connections
|
|
using any of the protocols that support persistent connections.
|
|
|
|
When reaching the maximum limit, curl closes the oldest one in the cache to
|
|
prevent increasing the number of open connections.
|
|
|
|
If you already have performed transfers with this curl handle, setting a
|
|
smaller CURLOPT_MAXCONNECTS(3) than before may cause open connections to
|
|
get closed unnecessarily.
|
|
|
|
If you add this easy handle to a multi handle, this setting is not
|
|
acknowledged, and you must instead use curl_multi_setopt(3) and the
|
|
CURLMOPT_MAXCONNECTS(3) option.
