curl_multi_socket_all(3)

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
CURLMcode type, general libcurl multi interface error code.

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.
