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_FILETIME - get the remote time of the retrieved document
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_FILETIME, long *timep);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
Pass a pointer to a long to receive the remote time of the retrieved document
|
|
in number of seconds since January 1 1970 in the GMT/UTC time zone. If you get
|
|
-1, it can be because of many reasons (it might be unknown, the server might
|
|
hide it or the server does not support the command that tells document time
|
|
etc) and the time of the document is unknown.
|
|
|
|
You must tell libcurl to collect this information before the transfer is made,
|
|
by using the CURLOPT_FILETIME(3) option to curl_easy_setopt(3) or
|
|
you this unconditionally gets a -1 back.
|
|
|
|
Consider using CURLINFO_FILETIME_T(3) to be able to extract dates beyond
|
|
the year 2038 on systems using 32 bit longs (Windows).
