7.3.5 Writing to Files

You can write the contents of a buffer, or part of a buffer, directly to a file on disk using the functions:

• append-to-file
• write-region

But don’t use these functions to write to files that are being visited.

• append-to-file
• write-region
• with-temp-file
• make-temp-file
• temporary-file-directory—a user option
• small-temporary-file-directory—a user option
