I read the document:
https://curl.haxx.se/libcurl/c/curl_multi_socket_action.html

It's function is:

curl_multi_socket_action(CURLM * multi_handle,
                         *curl_socket_t sockfd*,
                         int ev_bitmask,
                         int *running_handles);

It always said that we can set to the socket *sockfd *with *action*, it
doesn't mentioned what's the functionality of *sockfd *in the function.That
makes me confused.

the arguments *sockfd *is for libcurl to communicate with the user
specified url?
