mm-insert-file-contents

mm-insert-file-contents is a compiled Lisp function in `mm-util.el'.

(mm-insert-file-contents FILENAME &optional VISIT BEG END REPLACE INHIBIT)

Like `insert-file-contents', but only reads in the file.
A buffer may be modified in several ways after reading into the buffer due
to advanced Emacs features, such as file-name-handlers, format decoding,
`find-file-hooks', etc.
If INHIBIT is non-nil, inhibit `mm-inhibit-file-name-handlers'.
This function ensures that none of these modifications will take place.
