plucky (3) curl_multi_socket_all.3.gz

NAME

       curl_multi_socket_all - reads/writes available data for all easy handles

SYNOPSIS

       #include <curl/curl.h>

       CURLMcode curl_multi_socket_all(CURLM *multi_handle,
                                       int *running_handles);

DESCRIPTION

       This function is deprecated for performance reasons but there are no plans to remove it from the API. Use
       curl_multi_socket_action(3) instead.

       At return, the integer running_handles points to contains the number of still running easy handles within
       the multi handle. When this number reaches zero, all transfers are complete/done.

       Force  libcurl  to  (re-)check  all  its  internal  sockets and transfers instead of just a single one by
       calling curl_multi_socket_all(3). Note that there should not be any reason to use this function.

PROTOCOLS

       This functionality affects all supported protocols

EXAMPLE

       int main(void)
       {
         int running;
         int rc;
         CURLM *multi;
         rc = curl_multi_socket_all(multi, &running);
       }

AVAILABILITY

       Added in curl 7.15.4

RETURN VALUE

       This function returns a CURLMcode indicating success or error.

       CURLM_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3).

       The return code is for the whole multi stack. Problems still might have occurred on individual  transfers
       even when one of these functions return OK.
