Hi,
 I have removed the line and used the following lines of code with
libcurl version 7.19.7 on AIX 5.3 OS

        CURL *curl_handle;

      static const char *headerfilename = "head.out";

      FILE *headerfile;

      static const char *bodyfilename = "body.out";

      FILE *bodyfile;

      curl_global_init(CURL_GLOBAL_ALL);

       curl_handle = curl_easy_init();

      CURLcode retCode = CURLE_OK ;

      const char *pErrMsg = NULL;

      /* Setting Proxy*/

      retCode = curl_easy_setopt(curl_handle, CURLOPT_PROXY, "");

      /* set URL to get */

      retcode = curl_easy_setopt(curl_handle, CURLOPT_URL,
"http://m.in.yahoo.com/?p=us");

      /* no progress meter please */

      retCode = curl_easy_setopt(curl_handle, CURLOPT_NOPROGRESS, 1L);

      
      /* open the files */

      //headerfile = fopen(headerfilename,"w");

      headerfile = fopen("/homes/head.out","w");

      if (headerfile == NULL)

      {

            curl_easy_cleanup(curl_handle);

            return -1;

      }

      bodyfile = fopen("/homes/ body.out","w");

      if (bodyfile == NULL)

      {

            curl_easy_cleanup(curl_handle);

            return -1; }

      /* we want the headers to this file handle */

      retCode = curl_easy_setopt(curl_handle, CURLOPT_WRITEHEADER,
headerfile);

      retCode = curl_easy_setopt(curl_handle, CURLOPT_WRITEDATA,
(FILE*)bodyfile);

      /* get it! */

      retCode = curl_easy_perform(curl_handle);

      /* close the header file */

      fclose(headerfile);

      /* cleanup curl stuff */

      curl_easy_cleanup(curl_handle);

Still I am not getting the information in body.out file.

I could see that the stream is getting retrieved inside write_data
function but its not written to the file.

size_t write_data(void *ptr, size_t size, size_t nmemb, void *stream) {
  char* cptr = (char*)ptr;
  cout << cptr << endl;
  cout << cptr << endl;
  int written = fwrite(ptr, size, nmemb, (FILE *)stream);
  return written;
}

Please let me know if you can give me some inputs why this information
is not getting written into the file stream in UNIX.

Hi,

      I am using libcurl version 7.19.7 . I have tried the following
piece of code to retrieve the header & body information of the a website
with Mozila firebox 5.0 in AIX 5.3 OS

      CURL *curl_handle;

      static const char *headerfilename = "head.out";

      FILE *headerfile;

      static const char *bodyfilename = "body.out";

      FILE *bodyfile;

      curl_global_init(CURL_GLOBAL_ALL);

      /* init the curl session */

      curl_handle = curl_easy_init();

      CURLcode retCode = CURLE_OK ;

      const char *pErrMsg = NULL;

      /* Setting Proxy*/

      retCode = curl_easy_setopt(curl_handle, CURLOPT_PROXY, "");

      pErrMsg = curl_easy_strerror(retCode);

      /* set URL to get */

      retcode = curl_easy_setopt(curl_handle, CURLOPT_URL,
"http://m.in.yahoo.com/?p=us");

      pErrMsg = curl_easy_strerror(retCode);

      /* no progress meter please */

      retCode = curl_easy_setopt(curl_handle, CURLOPT_NOPROGRESS, 1L);

      pErrMsg = curl_easy_strerror(retCode);

      /* send all data to this function */

      retCode =curl_easy_setopt(curl_handle, CURLOPT_WRITEFUNCTION,
write_data);

      pErrMsg = curl_easy_strerror(retCode);

      /* open the files */

      //headerfile = fopen(headerfilename,"w");

      headerfile = fopen("/homes/head.out","w");

      if (headerfile == NULL)

      {

            curl_easy_cleanup(curl_handle);

            return -1;

      }

      bodyfile = fopen("/homes/ body.out","w");

      if (bodyfile == NULL)

      {

            curl_easy_cleanup(curl_handle);

            return -1; }

      /* we want the headers to this file handle */

      retCode = curl_easy_setopt(curl_handle, CURLOPT_WRITEHEADER,
headerfile);

      pErrMsg = curl_easy_strerror(retCode);

      /*

      * Notice here that if you want the actual data sent anywhere else
but

      * stdout, you should consider using the CURLOPT_WRITEDATA option.
*/

      retCode = curl_easy_setopt(curl_handle, CURLOPT_WRITEDATA,
bodyfile);

      pErrMsg = curl_easy_strerror(retCode);

      /* get it! */

      retCode = curl_easy_perform(curl_handle);

      pErrMsg = curl_easy_strerror(retCode);

      /* close the header file */

      fclose(headerfile);

      /* cleanup curl stuff */

      curl_easy_cleanup(curl_handle);

I am not able to retrieve the header & body information using the above
piece of code. I didn't get any error message using CURLcode.

I got the content of head.out as

HTTP/1.1 200 OK

content-language: en-US

content-type: text/html;charset=ISO-8859-1

date: Thu, 31 Dec 2009 11:27:15 GMT

Path=/

& the empty information in body.out file.

On the other hand, I have performed the same operation in Windows with
Internet explorer and I am able to retrieve the header and body
information without any issues.

Request you to please let me know whether I need to set any specific
settings for my Unix development.

Hi,

> write_data);

You are overriding the default write function here.

[snipped the header information]

Do you get something in body.out if you remove the above line in your
code?

Best regards,
Julien
