It's mostly a filler word. I've read through each use of it in the code base and did minor rephrasings when "simply" carried some meaning. The overwhelming majority of cases, removing it improved the text significantly. Inspired by #20793. Closes #20822

# NAME
|
|
|
|
CURLMOPT_MAXCONNECTS - size of connection cache
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_MAXCONNECTS, long max);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
Pass a long indicating the **max**, the maximum amount of connections that
|
|
libcurl may keep alive in its connection cache after use. By default libcurl
|
|
enlarges the size for each added easy handle to make it fit 4 times the number
|
|
of added easy handles.
|
|
|
|
By setting this option, you prevent the cache size from growing beyond the
|
|
limit set by you.
|
|
|
|
When the cache is full, curl closes the oldest connection present in the cache
|
|
to prevent the number of connections from increasing.
|
|
|
|
This option is for the multi handle's use only, when using the easy interface
|
|
you should instead use the CURLOPT_MAXCONNECTS(3) option.
|
|
|
|
See CURLMOPT_MAX_TOTAL_CONNECTIONS(3) for limiting the number of active
|
|
connections.
|
|
|
|
Changing this value when there are transfers in progress is possible, and the
|
|
new value is then used the next time checks are performed. Lowering the value
|
|
does not close down any active transfers, it prevents new ones from being
|
|
made.

# RETURN VALUE

CURLM_OK (0) means everything was OK, non-zero means an error occurred, see
|
|
