It is completely broken. I suggest you read up the libcurl documentation
first, and then base your initial attempts on an existing example.

You may also want to go back to read up on how you actually write C code. I'll
detail some of the problems below:

CURLOPT_WRITEFUNCTION sets a pointer to a callback function, it should not be
an uninitialized char *.

There's no need to free a NULL pointer.

You really should check the return code!

For waiting? What? That's not at all what you should do. The "sending" and
"receiving" parts of your code are completely wrong. curl_easy_perform()
already did both.

Lack of proper header file.

Lack of proper struct declaration

Lack of proper header file

Weirdly formatted string.

Bad syntax.

Wrong syntax.
