NAME

curl_multi_init - create a multi handle

SYNOPSIS

#include <curl/curl.h>

CURLM *curl_multi_init();

DESCRIPTION

This function returns a pointer to a CURLM handle to be used as input to all the other multi-functions, sometimes referred to as a multi handle in some places in the documentation. This init call MUST have a corresponding call to curl_multi_cleanup(3) when the operation is complete.

EXAMPLE

int main(void)
{
  /* init a multi stack */
  CURLM *multi = curl_multi_init();
  CURL *curl = curl_easy_init();
  CURL *curl2 = curl_easy_init();

  /* add individual transfers */
  curl_multi_add_handle(multi, curl);
  curl_multi_add_handle(multi, curl2);
}

AVAILABILITY

Added in 7.9.6

RETURN VALUE

If this function returns NULL, something went wrong and you cannot use the other curl functions.
