Dear all,

I am very new to LibCurl, and am struggling with the CURLOPT_WRITEFUNCTION
function.

I have included my source code below, but essentially my issue is here:

/*

                                printf("\n");

                                printf(response.c_str());

                                printf("\n");

                                LogToDisk(response);

*/

The function that stores the data to a string seems to print the entire
string out perfectly fine on the console using “printf”. However, when it
saves to disc file, there is a large amount of text missing. Can anyone help
me understand what I am doing wrong?

I noticed that there is an extremely long string in the html of the page I
am going to, and this is also where is just stops working…

Here is an example of the last line where the file stops writing and gives
up (I put the last part in bold), it should continue waaaay past this…:
