.SH NAME
|
||
|
|
curl_multi_socket_all \- reads/writes available data for all easy handles
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLMcode curl_multi_socket_all(CURLM *multi_handle,
|
||
|
|
int *running_handles);
|
||
|
|
.fi
|
||
|
|
.SH DESCRIPTION
|
||
|
|
This function is deprecated for performance reasons but there are no plans to
|
||
|
|
remove it from the API. Use \fIcurl_multi_socket_action(3)\fP instead.
|
||
|
|
|
||
|
|
At return, the integer \fBrunning_handles\fP 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 \fIcurl_multi_socket_all(3)\fP. Note that there should
|
||
|
|
not be any reason to use this function.
|
||
|

.SH EXAMPLE
|
||
|

int main(void)
|
||
|
|
{
|
||
|
|
int running;
|
||
|
|
int rc;
|
||
|
|
CURLM *multi = curl_multi_init();
|

.SH AVAILABILITY
|
||
|
|
Added in curl 7.15.4
|
||
|
|
.SH 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
|
||
|
|
\fIlibcurl\-errors(3)\fP.
|
||
|
|
|
||
|
|
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.
