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
|
|
|
|
CURLINFO_SSL_ENGINES - get an slist of OpenSSL crypto-engines
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SSL_ENGINES,
|
|
struct curl_slist **engine_list);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
Pass the address of a 'struct curl_slist *' to receive a linked-list of
|
|
OpenSSL crypto-engines supported. Note that engines are normally implemented
|
|
in separate dynamic libraries. Hence not all the returned engines may be
|
|
available at runtime. **NOTE:** you must call curl_slist_free_all(3)
|
|
on the list pointer once you are done with it, as libcurl does not free this
|
|
data for you.
|
|
|
|
# PROTOCOLS
|
|
|
|
All TLS based ones.
|
|
|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
int main(void)
|
|
{
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
CURLcode res;
|
|
struct curl_slist *engines;
|
|
res = curl_easy_getinfo(curl, CURLINFO_SSL_ENGINES, &engines);
|
|
if((res == CURLE_OK) && engines) {
|
|
/* we have a list, free it when done using it */
|
|
curl_slist_free_all(engines);
|
|
}
|
|
|
|
curl_easy_cleanup(curl);
|
|
}
|
|
}
|
|
~~~
|
|
|
|
# AVAILABILITY
|
|
|
|
Added in 7.12.3. Available in OpenSSL builds with "engine" support.
|
|
|
|
# RETURN VALUE
|
|
|
|
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
