curl_multi_socket_all(3) Introduction to Library Functions

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.
