Question

Explain file open and close functions with arguments

Answer 1

23.2. Opening and Closing Files

When a file is opened, a stream object is constructed to serve as the file system's ambassador to the Lisp environment; operations on the stream are reflected by operations on the file in the file system. The act of closing the file (actually, the stream) ends the association; the transaction with the file system is terminated, and input/output may no longer be performed on the stream. The stream function close may be used to close a file; the functions described below may be used to open them. The basic operation is open, but with-open-file is usually more convenient for most applications.
