Expand a little. - mention the type name of the return code - avoid stating which exact return codes that might be returned, as that varies over time, builds and conditions - avoid stating some always return OK - refer to the manpage documenting all the return codes Closes #15900

# NAME
|
|
|
|
CURLOPT_IGNORE_CONTENT_LENGTH - ignore content length
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_IGNORE_CONTENT_LENGTH,
|
|
long ignore);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
If *ignore* is set to 1L, ignore the Content-Length header in the HTTP
|
|
response and ignore asking for or relying on it for FTP transfers.
|
|
|
|
This is useful for doing HTTP transfers with ancient web servers which report
|
|
incorrect content length for files over 2 gigabytes. If this option is used,
|
|
curl cannot accurately report progress, and it instead stops the download when
|
|
the server ends the connection.
|
|
|
|
It is also useful with FTP when for example the file is growing while the
|
|
transfer is in progress which otherwise unconditionally causes libcurl to
|
|
report error.
|
|
|
|
Only use this option if strictly necessary.

if(curl) {
|
|
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
|
|
|
|
/* we know the server is silly, ignore content-length */
|
|
curl_easy_setopt(curl, CURLOPT_IGNORE_CONTENT_LENGTH, 1L);
|
|
|
|
curl_easy_perform(curl);
|
|
}
