25 (defun insert-file-contents (filename &optional visit beg end replace)
26 "Insert contents of file FILENAME after point.
27 Returns list of absolute file name and length of data inserted.
28 If second argument VISIT is non-nil, the buffer's visited filename
29 and last save file modtime are set, and it is marked unmodified.
30 If visiting and the file does not exist, visiting is completed
31 before the error is signaled.
32
33 The optional third and fourth arguments BEG and END
34 specify what portion of the file to insert.
35 If VISIT is non-nil, BEG and END must be nil.
36 If optional fifth argument REPLACE is non-nil,
37 it means replace the current buffer contents (in the accessible portion)
38 with the file contents. This is better than simply deleting and inserting
39 the whole thing because (1) it preserves some marker positions
40 and (2) it puts less data in the undo list."

43 (defun write-region (start end filename &optional append visit lockname)
44 "Write current region into specified file.
45 When called from a program, takes three arguments:
46 START, END and FILENAME. START and END are buffer positions.
47 Optional fourth argument APPEND if non-nil means
48 append to existing file contents (if any).
49 Optional fifth argument VISIT if t means
50 set the last-save-file-modtime of buffer to this file's modtime
51 and mark buffer not modified.
52 If VISIT is a string, it is a second file name;
53 the output goes to FILENAME, but the buffer is marked as visiting VISIT.
54 VISIT is also the file name to lock and unlock for clash detection.
55 If VISIT is neither t nor nil nor a string,
56 that means do not print the \"Wrote file\" message.
57 The optional sixth arg LOCKNAME, if non-nil, specifies the name to
58 use for locking and unlocking, overriding FILENAME and VISIT.
59 Kludgy feature: if START is a string, then that string is written
60 to the file, instead of any buffer contents, and END is ignored."

68 This function searches the directories in `load-path'.
69 If optional second arg NOERROR is non-nil,
70 report no error if FILE doesn't exist.
71 Print messages at start and end of loading unless
72 optional third arg NOMESSAGE is non-nil (ignored in -batch mode).
73 If optional fourth arg NOSUFFIX is non-nil, don't try adding
74 suffixes `.elc' or `.el' to the specified name FILE.
