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...

# NAME
|
|
|
|
CURLOPT_SHARE - share handle to use
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SHARE, CURLSH *share);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
Pass a *share* handle as a parameter. The share handle must have been
|
|
created by a previous call to curl_share_init(3). Setting this option,
|
|
makes this curl handle use the data from the shared handle instead of keeping
|
|
the data to itself. This enables several curl handles to share data. If the
|
|
curl handles are used simultaneously in multiple threads, you **MUST** use
|
|
the locking methods in the share handle. See curl_share_setopt(3) for
|
|
details.
|
|
|
|
If you add a share that is set to share cookies, your easy handle uses that
|
|
cookie cache and get the cookie engine enabled. If you stop sharing an object
|
|
that was using cookies (or change to another object that does not share
|
|
cookies), the easy handle gets its cookie engine disabled.
|
|
|
|
Data that the share object is not set to share is dealt with the usual way, as
|
|
if no share was used.
|
|
|
|
Set this option to NULL again to stop using that share object.
