20curl_multi_socket_all - reads/writes available data for all easy handles
21
22# SYNOPSIS
23
24~~~c
25#include <curl/curl.h>
26
27CURLMcode curl_multi_socket_all(CURLM *multi_handle,
28                                int *running_handles);

31# DESCRIPTION
32
33This function is deprecated. Do not use. See curl_multi_socket_action(3)
34instead.
35
36At return, the integer **running_handles** points to contains the number of
37still running easy handles within the multi handle. When this number reaches
38zero, all transfers are complete/done.
39
40Force libcurl to (re-)check all its internal sockets and transfers instead of
41just a single one by calling curl_multi_socket_all(3). Note that there should
42not be any reason to use this function.

61
62CURLMcode type, general libcurl multi interface error code.

64The return code is for the whole multi stack. Problems still might have
65occurred on individual transfers even when one of these functions return OK.
