NAME

       curl_multi_setopt - set options for a curl multi handle

SYNOPSIS

       #include <curl/curl.h>

       CURLMcode curl_multi_setopt(CURLM *multi_handle, CURLMoption option, parameter);

DESCRIPTION

       curl_multi_setopt(3)  is  used  to tell a libcurl multi handle how to behave. By using the
       appropriate options to curl_multi_setopt(3), you can change libcurl's behavior when  using
       that  multi  handle.  All  options are set with the option followed by the parameter. That
       parameter can be a long, a function pointer, an  object  pointer  or  a  curl_off_t  type,
       depending  on  what  the  specific option expects. Read this manual carefully as bad input
       values may cause libcurl to behave badly. You can only set one  option  in  each  function
       call.

       int main(void)
       {
         CURLM *multi;

AVAILABILITY

RETURN VALUE

       The  standard  CURLMcode  for  multi  interface  error  codes.  Note  that  it  returns  a
       CURLM_UNKNOWN_OPTION if you try setting an option that this version of  libcurl  does  not
       know of.
