CURLOPT_TIMEOUT(3) curl_easy_setopt options CURLOPT_TIMEOUT(3)NAMECURLOPT_TIMEOUT - set maximum time the request is allowed to take
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TIMEOUT, long timeout);
DESCRIPTION
Pass a long as parameter containing timeout - the maximum time in sec‐
onds 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.
In unix-like systems, this might cause signals to be used unless CUR‐
LOPT_NOSIGNAL(3) is set.
If both CURLOPT_TIMEOUT(3) and CURLOPT_TIMEOUT_MS(3) 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 CURLOPT_LOW_SPEED_LIMIT(3), CUR‐
LOPT_LOW_SPEED_TIME(3) or using CURLOPT_PROGRESSFUNCTION(3) to imple‐
ment your own timeout logic.
DEFAULT
Default timeout is 0 (zero) which means it never times out during
transfer.
