.TH CURLOPT_TIMEOUT 3 "November 04, 2020" "libcurl 7.77.0" "curl_easy_setopt options"

.SH NAME
CURLOPT_TIMEOUT \- set maximum time the request is allowed to take
.SH SYNOPSIS
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TIMEOUT, long timeout);
.SH DESCRIPTION
Pass a long as parameter containing \fItimeout\fP - the maximum time in
seconds that you allow the libcurl transfer operation to take. Normally, name
lookups can take a considerable time and limiting operations risk aborting
perfectly normal operations. This option may cause libcurl to use the SIGALRM
signal to timeout system calls.

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 option puts a hard limit on how long time a request is allowed to
take, it has limited use in dynamic use cases with varying transfer times. That
is especially apparent when using the multi interface, which may queue the
transfer, and that time is included. You are 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
All
.SH EXAMPLE
.nf
CURL *curl = curl_easy_init();
if(curl) {
  curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

  /* complete within 20 seconds */
  curl_easy_setopt(curl, CURLOPT_TIMEOUT, 20L);

  curl_easy_perform(curl);
}
.fi
.SH AVAILABILITY
Always
.SH RETURN VALUE
Returns CURLE_OK. Returns CURLE_BAD_FUNCTION_ARGUMENT if set to a negative
value or a value that when converted to milliseconds is too large.

.BR CURLOPT_TIMEOUT_MS "(3), "
.BR CURLOPT_CONNECTTIMEOUT "(3), " CURLOPT_LOW_SPEED_LIMIT "(3), "
