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_SSL_VERIFYSTATUS - verify the certificate's status
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_VERIFYSTATUS, long verify);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
Pass a long as parameter set to 1 to enable or 0 to disable.
|
|
|
|
This option determines whether libcurl verifies the status of the server cert
|
|
using the "Certificate Status Request" TLS extension (aka. OCSP stapling).
|
|
|
|
Note that if this option is enabled but the server does not support the TLS
|
|
extension, the verification fails.
|
|
|
|
# DEFAULT
|
|
|
|
0
|
|
|
|
# PROTOCOLS
|
|
|
|
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
|
|
|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
int main(void)
|
|
{
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
CURLcode res;
|
|
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
|
|
/* ask for OCSP stapling! */
|
|
curl_easy_setopt(curl, CURLOPT_SSL_VERIFYSTATUS, 1L);
|
|
res = curl_easy_perform(curl);
|
|
curl_easy_cleanup(curl);
|
|
}
|
|
}
|
|

|
|
|
|
# AVAILABILITY
|
|
|
|
Added in 7.41.0. This option is currently only supported by the OpenSSL and
|
|
GnuTLS TLS backends.
|
|
|
|
# RETURN VALUE
|
|
|
|
Returns CURLE_OK if OCSP stapling is supported by the SSL backend, otherwise
|
|
returns CURLE_NOT_BUILT_IN.
