curl_multi_socket_all(3)   Library Functions Manual   curl_multi_socket_all(3)

NAME
       curl_multi_socket_all  -	 reads/writes available	data for all easy han-
       dles

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) in-
       stead.

       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 in-
       stead 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 re-
       turn OK.
