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

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.

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