Problemm with separating header and data using curl

[Khushi]

Hi,

This is Khushi, i'm trying with a sample code to get header separately into a file for continous streaming urls. but am not to get it.. both the header and data information are present in the body.out file.
I'm pasting my sample code here..

##

FILE *bodyfile;
FILE *headerfile;

CURL *curl_handle;
int responsebytes_written = 0;
static size_t write_data(void *ptr, size_t size, size_t nmemb, void *stream)
{
responsebytes_written = fwrite(ptr, size, nmemb, (FILE *)stream);
printf("bytes written %d\n", responsebytes_written);
return responsebytes_written;
}

static size_t write_header(void *ptr, size_t size, size_t nmemb, void *stream)
{
int written = fwrite(ptr, size, nmemb, (FILE *)stream);
printf("bytes written in header %d\n", written);
return written;
}

static size_t progressfun(void *ptr, size_t size, size_t nmemb, void *stream)
{
CURL *curl_handle1;
int ret = 0;
static int progresscnt = 0;
int written = fwrite(ptr, size, nmemb, (FILE *)stream);


//if(responsebytes_written == 0)
{
progresscnt++;
}
/* else
{
responsebytes_written = 0;
}*/
printf("progress fun %d %d\n", written, progresscnt);
#if 0
if(progresscnt == 10)
{

printf("Interface has gone down!!!!!!!!!!!!!!!!!!\n");

#if 1
// curl_easy_cleanup(curl_handle);
curl_handle1 = curl_easy_init();
curl_easy_setopt(curl_handle1, CURLOPT_VERBOSE, 1);
curl_easy_setopt(curl_handle1, CURLOPT_INTERFACE, "em1");
//curl_easy_setopt(curl_handle1, CURLOPT_FRESH_CONNECT, "eth0");
printf("handle is %d\n", curl_handle);
curl_easy_setopt(curl_handle1, CURLOPT_URL,"http://www.google.co.in");


//curl_easy_setopt(curl_handle1, CURLOPT_URL,"http://scfire-dtc-aa03.stream.aol.com:80/stream/1010");
curl_easy_setopt(curl_handle1,CURLOPT_WRITEHEADER, headerfile);

/* we want the headers to this file handle */
curl_easy_setopt(curl_handle1, CURLOPT_HEADERFUNCTION, write_header);
curl_easy_setopt(curl_handle1, CURLOPT_WRITEDATA, bodyfile);
/* send all data to this function */
curl_easy_setopt(curl_handle1, CURLOPT_WRITEFUNCTION, write_data);
#if 1
curl_easy_setopt(curl_handle1, CURLOPT_PROXY, "proxy.tcs.com:8080");
curl_easy_setopt(curl_handle1, CURLOPT_PROXYUSERNAME , "522528");
curl_easy_setopt(curl_handle1, CURLOPT_PROXYPASSWORD , "Ggupsp@2911");
#endif


curl_easy_setopt(curl_handle1, CURLOPT_NOPROGRESS, 0);
curl_easy_setopt(curl_handle1, CURLOPT_PROGRESSFUNCTION, progressfun);
printf("before easy perform handle1\n");
ret = curl_easy_perform(curl_handle1);
printf("after easy perform handle1 %d\n", ret);
#endif
progresscnt = 31;
}
#endif
return written;
}
//curl_sockopt_callback fsockcb;
int fsockcb (void *clientp,curl_socket_t curlfd,curlsocktype purpose)
{
int ret =0 ;
printf("socket id is %d\n", curlfd);
if(ret = setsockopt(curlfd, SOL_SOCKET, SO_BINDTODEVICE,
"em1", (curl_socklen_t)(strlen(("em1")+1))) != 0) {
// error = SOCKERRNO;
}
printf("am hereeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee %d\n", errno);
return 0;
}

int main(void)
{

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

static const char *bodyfilename = "body.out";
int ret = 0;

/* open the files */
headerfile = fopen(headerfilename,"w");
if (headerfile == NULL) {
// curl_easy_cleanup(curl_handle);
printf("headerfile open failed\n");
return -1;
}
bodyfile = fopen(bodyfilename,"w");

printf("bodyfile open failed\n");
return -1;
}


curl_global_init(CURL_GLOBAL_ALL);

/* init the curl session */
curl_handle = curl_easy_init();

/* set URL to get */

curl_easy_setopt(curl_handle, CURLOPT_VERBOSE, 1);
//curl_easy_setopt(curl_handle, CURLOPT_INTERFACE, "em1");

/* no progress meter please */

curl_easy_setopt(curl_handle, CURLOPT_NOPROGRESS, 0);

curl_easy_setopt(curl_handle, CURLOPT_PROXYUSERNAME , "INDIA\\522528");
curl_easy_setopt(curl_handle, CURLOPT_PROXYPASSWORD , "Ggupsp@2911");
#endif

/*
* Notice here that if you want the actual data sent anywhere else but
* stdout, you should consider using the CURLOPT_WRITEDATA option. */

/* get it! */

printf("before main easy perform\n");
ret = curl_easy_perform(curl_handle);

printf("after main easy perform %d %d\n", ret, errno);
/* close the header file */
fclose(headerfile);
fclose(bodyfile);

/* cleanup curl stuff */
curl_easy_cleanup(curl_handle);

return 0;
}

Please do go through and help me in finding a solutions..thanks in advance...
waiting for responses..

I think you're probably looking for help with libcurl, which is occasionally confused with the language / runtime environment Curl.

Perhaps try: http://curl.haxx.se/

Thanks for the reply.. can u tell me few other solutions so that i can try with that too..

Sorry if there is some continuing confusion, but I meant you should probably try asking at forums or lists for the actual software. This forum is for an entirely unrelated product (though it's certainly possible that some of our visitors also use cURL too!).

There's a mailing list for libcurl users at: http://curl.haxx.se/mail/list.cgi?list=curl-library
