23 .TH CURLOPT_TIMEOUT 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
25 CURLOPT_TIMEOUT \- set maximum time the request is allowed to take
27 #include <curl/curl.h>
29 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TIMEOUT, long timeout);
31 Pass a long as parameter containing \fItimeout\fP - the maximum time in
32 seconds that you allow the libcurl transfer operation to take. Normally, name
33 lookups can take a considerable time and limiting operations to less than a
34 few minutes risk aborting perfectly normal operations. This option may cause
35 libcurl to use the SIGALRM signal to timeout system calls.
37 In unix-like systems, this might cause signals to be used unless
38 \fICURLOPT_NOSIGNAL(3)\fP is set.
40 If both \fICURLOPT_TIMEOUT(3)\fP and \fICURLOPT_TIMEOUT_MS(3)\fP are set, the
41 value set last will be used.
43 Since this puts a hard limit for how long time a request is allowed to take,
44 it has limited use in dynamic use cases with varying transfer times. You are
45 then advised to explore \fICURLOPT_LOW_SPEED_LIMIT(3)\fP,
46 \fICURLOPT_LOW_SPEED_TIME(3)\fP or using \fICURLOPT_PROGRESSFUNCTION(3)\fP to
47 implement your own timeout logic.
49 Default timeout is 0 (zero) which means it never times out during transfer.
