36 (defun insert-file-contents (filename &optional visit beg end replace)
37 "Insert contents of file FILENAME after point.
38 Returns list of absolute file name and length of data inserted.
39 If second argument VISIT is non-nil, the buffer's visited filename
40 and last save file modtime are set, and it is marked unmodified.
41 If visiting and the file does not exist, visiting is completed
42 before the error is signaled.
43
44 The optional third and fourth arguments BEG and END
45 specify what portion of the file to insert.
46 If VISIT is non-nil, BEG and END must be nil.
47 If optional fifth argument REPLACE is non-nil,
48 it means replace the current buffer contents (in the accessible portion)
49 with the file contents. This is better than simply deleting and inserting
50 the whole thing because (1) it preserves some marker positions
51 and (2) it puts less data in the undo list."
52 (insert-file-contents-internal filename visit beg end replace nil nil))
53
54 (defun write-region (start end filename &optional append visit lockname coding-system)
55 "Write current region into specified file.
56 By default, the file's existing contents are replaced by the specified region.
57 When called from a program, takes three arguments:
58 START, END and FILENAME. START and END are buffer positions.
59 Optional fourth argument APPEND if non-nil means
60 append to existing file contents (if any).
61 Optional fifth argument VISIT if t means
62 set the last-save-file-modtime of buffer to this file's modtime
63 and mark buffer not modified.
64 If VISIT is a string, it is a second file name;
65 the output goes to FILENAME, but the buffer is marked as visiting VISIT.
66 VISIT is also the file name to lock and unlock for clash detection.
67 If VISIT is neither t nor nil nor a string,
68 that means do not print the \"Wrote file\" message.
69 The optional sixth arg LOCKNAME, if non-nil, specifies the name to
70 use for locking and unlocking, overriding FILENAME and VISIT.
71 Kludgy feature: if START is a string, then that string is written
72 to the file, instead of any buffer contents, and END is ignored.
73 Optional seventh argument CODING-SYSTEM is meaningful only if support
74 for Mule is present in XEmacs and specifies the coding system
75 used to encode the text when it is written out, and defaults to
76 the value of `buffer-file-coding-system' in the current buffer.
77 When Mule support is not present, the CODING-SYSTEM argument is
78 ignored."
79 (interactive "r\nFWrite region to file: ")

82 (defun load (file &optional noerror nomessage nosuffix)
83 "Execute a file of Lisp code named FILE.
84 First try FILE with `.elc' appended, then try with `.el',
85 then try FILE unmodified.
86 This function searches the directories in `load-path'.
87 If optional second arg NOERROR is non-nil,
88 report no error if FILE doesn't exist.
89 Print messages at start and end of loading unless
90 optional third arg NOMESSAGE is non-nil (ignored in -batch mode).
91 If optional fourth arg NOSUFFIX is non-nil, don't try adding
92 suffixes `.elc' or `.el' to the specified name FILE.
93 Return t if file exists."
