You can call this function to close the connection that was used by CURL and to release all resources that were allocated to handle the connection. To call this function is not a must as all the releasing tasks are automatically performed as soon as the interpreter finishes execution the BASIC program. However it is a good practice to call this functions especially if you want to access the file the perform routine downloaded.
Usage:
curl::finish CURL
This function closes the connection to the remote URL, closes the local file (if there was opened any), and releases the memory that was used for the connection.
