CURLOPT_TIMEOUT - maximum time the transfer is allowed to complete
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TIMEOUT, long timeout);
Pass a long as parameter containing
timeout - 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
CURLOPT_NOSIGNAL(3) is set.
If both and
CURLOPT_TIMEOUT_MS(3) 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
CURLOPT_LOW_SPEED_LIMIT(3),
CURLOPT_LOW_SPEED_TIME(3) or using
CURLOPT_PROGRESSFUNCTION(3) to implement your own timeout logic.
Default timeout is 0 (zero) which means it never times out during transfer.

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.
