CURLOPT_TIMEOUT_MS(3) curl_easy_setopt options CURLOPT_TIMEOUT_MS(3) NAME CURLOPT_TIMEOUT_MS - maximum time the transfer is allowed to complete SYNOPSIS #include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TIMEOUT_MS, long timeout); DESCRIPTION Pass a long as parameter containing timeout - the maximum time in mil- liseconds that you allow the libcurl transfer operation to take. Nor- mally, name lookups can take a considerable time and limiting opera- tions to less than a few minutes risk aborting perfectly normal opera- tions. This option may cause libcurl to use the SIGALRM signal to time- out system calls. If libcurl is built to use the standard system name resolver, that por- tion 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 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.
