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 = curl_multi_init();

  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.
