Help needed with curl library

anuRV · 12-06-2013, 10:57 AM

Hi,

I am trying to post the current-time using curl library.

curl_formadd(&formpost,
&lastptr,
CURLFORM_COPYNAME, "ts",
CURLFORM_COPYCONTENTS, getCurrentTime(), //error!!
CURLFORM_END);

//getCurrentTime() is a method that returns string.

Can anyone help me with how I can do this. I am pretty new to curl.
Any help in this would be highly appreciated.

Thanks in advance!!

From man curl_formadd:

Code:

       CURLFORM_COPYCONTENTS
              followed by a pointer to the contents of this part,  the  actual
              data  to  send  away.  libcurl copies the provided data, so your
              application doesn't need to keep it around after  this  function
              call.  If the data isn't null terminated, or if you'd like it to
              contain zero bytes, you must set the length  of  the  name  with
              CURLFORM_CONTENTSLENGTH.  The  copied  data  will  be  freed  by
              curl_formfree(3).

It would appear that getCurrentTime() needs to be called before the call to curl_formadd(). I'm assuming that getCurrentTime() returns a character pointer, so try creating a character pointer to hold the return from getCurrentTime() and put the variable in the curl_formadd() call.
