Duda acerca libreria Curl C++

Gracias, aunque la verdad es que me confundí en el ejemplo jejeje, porque el ejemplo que puse es de recibir por HTTPS información.

Con el comando de "curl -o fichero_salida... " (ahora no sé cual es el comando exacto) pero se puede poner para que envie un fichero por HTTPS y a la vez recibir un fichero de confirmación del buen envio de mi fichero

Lo que yo no sé si poniendo lo que me puso #2 a un código parecido a este (que es el del envio de algo por HTTPS funciona.

(no se si me he explicado bien)
