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 +\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 +All +.SH EXAMPLE +.nf +CURL *curl = curl_easy_init(); +if(curl) { + curl_easy_setopt(curl, CURLOPT_URL, "http://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 +.SH "SEE ALSO" +.BR CURLOPT_TIMEOUT_MS "(3), " +.BR CURLOPT_CONNECTTIMEOUT "(3), " CURLOPT_LOW_SPEED_LIMIT "(3), " |
