curl_easy_perform(3) libcurl Manual curl_easy_perform(3)NAMEcurl_easy_perform - Perform a file transfer
CURLcode curl_easy_perform(CURL *handle);
This function is called after the init and all the curl_easy_setopt(3)
calls are made, and will perform the transfer as described in the
options. It must be called with the same handle as input as the
curl_easy_init call returned.
You can do any amount of calls to curl_easy_perform(3) while using the
same handle. If you intend to transfer more than one file, you are even
encouraged to do so. libcurl will then attempt to re-use the same con‐
nection for the following transfers, thus making the operations faster,
less CPU intense and using less network resources. Just note that you
will have to use curl_easy_setopt(3) between the invokes to set options
for the following curl_easy_perform.
You must never call this function simultaneously from two places using
the same handle. Let the function return first before invoking it
another time. If you want parallel transfers, you must use several curl
0 means everything was ok, non-zero means an error occurred as
<curl/curl.h> defines. If the CURLOPT_ERRORBUFFER was set with
curl_easy_setopt there will be a readable error message in the error
buffer when non-zero is returned.
