Hi,
I am trying to download files whose size is greater than 2GB using curl API's like curl_easy_perform ( ) and curl_easy_setopt ( ) on linux and unix platforms using c++ language.

The problem is, the above functions are helping me to download upto 2GB file size and not more than that.
Here what i am doing is................I am calling the statement:
curl_easy_setopt(curlHandle_m, CURLOPT_WRITEFUNCTION, FileTransfer::CallBack);

Then, it calls the CallBack function which tries to download the file part by part in bytes into the destination place.But once the file reaches 2GB size it is not able to write the remaining data into the file.

Following is the Callback function:
size_t FileTransfer::CallBack(void *buffer, size_t size, size_t nmemb, void *stream) {

struct DownloadFileName *out = (struct DownloadFileName *) stream;
if (out && !out->stream) {

LOG_DEBUG(ACE_TEXT("While downloading file name as: %s\n"), out->filename);

// open file for writing
out->stream = ACE_OS::fopen(out->filename, "wb");

if (!out->stream) {

// Failure, can't open file to write
return CURLE_WRITE_ERROR;
}
}
return ACE_OS::fwrite(buffer, size, nmemb, out->stream);
}

So plz anyone help me regarding this issue......

Thanks,
