.TH CURLOPT_IGNORE_CONTENT_LENGTH 3 "19 Jun 2014" libcurl libcurl
|
|
.SH NAME
|
|
CURLOPT_IGNORE_CONTENT_LENGTH \- ignore content length
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_IGNORE_CONTENT_LENGTH,
|
|
long ignore);
|
|
.SH DESCRIPTION
|
|
If \fIignore\fP 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.
|
|
.SH DEFAULT
|
|
0

.SH EXAMPLE
|
|
.nf
|
|
CURL *curl = curl_easy_init();
|
|
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);
|
|
}
|
|
.fi
|
|
.SH AVAILABILITY
|
|
Added in 7.14.1. Support for FTP added in 7.46.0. This option is not working
|
|
for HTTP when libcurl is built to use the hyper backend.
|
|
.SH RETURN VALUE
|
|
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
|
|
.SH "SEE ALSO"
