.TH CURLOPT_TIMEOUT_MS 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_TIMEOUT_MS \- set maximum time the request is allowed to take
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TIMEOUT_MS, long timeout);
|
|
.SH DESCRIPTION
|
|
Pass a long as parameter containing \fItimeout\fP - the maximum time in
|
|
milliseconds that you allow the libcurl transfer operation to take. Normally,
|
|
name lookups can take a considerable time and limiting operations to less than
|
|
a few minutes risk aborting perfectly normal operations. This option may cause
|
|
libcurl to use the SIGALRM signal to timeout system calls.
|
|
|
|
If libcurl is built to use the standard system name resolver, that portion of
|
|
the transfer will still use full-second resolution for timeouts with a minimum
|
|
timeout allowed of one second.
|
|
|
|
In unix-like systems, this might cause signals to be used unless
|
|
\fICURLOPT_NOSIGNAL(3)\fP is set.
|
|
|
|
If both \fICURLOPT_TIMEOUT(3)\fP and \fICURLOPT_TIMEOUT_MS(3)\fP are set, the
|
|
value set last will be used.
|
|
|
|
Since this puts a hard limit for how long time a request is allowed to take,
|
|
it has limited use in dynamic use cases with varying transfer times. You are
|
|
then advised to explore \fICURLOPT_LOW_SPEED_LIMIT(3)\fP,
|
|
\fICURLOPT_LOW_SPEED_TIME(3)\fP or using \fICURLOPT_PROGRESSFUNCTION(3)\fP to
|
|
implement your own timeout logic.
|
|
.SH DEFAULT
|
|
Default timeout is 0 (zero) which means it never times out during transfer.
|
|
.SH PROTOCOLS
|
|
