29.Sh NAME
30.Nm elftc_set_timestamps
31.Nd set file timestamps
32.Sh LIBRARY
33.Lb libelftc
34.Sh SYNOPSIS
35.In libelftc.h
36.Ft int
37.Fn elftc_set_timestamps "const char *filename" "struct stat *sb"
38.Sh DESCRIPTION
39The
40.Fn elftc_set_timestamps
41function is used to set the access and modified time stamps on a file
42based on the contents of a
43.Vt "struct stat"
44descriptor.
45.Pp
46Argument
47.Ar filename
48names an existing file in the file system.
49.Pp
50Argument
51.Ar sb
52points to structure of type
53.Vt "struct stat"
54populated by a prior call to
55.Xr fstat 2
56or
57.Xr stat 2 .
58.Sh IMPLEMENTATION NOTES
59This function will invoke the high-resolution
60.Xr utimes 2
61system call if the underlying operating system supports it.
62On operating systems lacking support for
63.Xr utimes 2 ,
64the function will use lower resolution
65.Xr utime 2
66system call.
67.Sh EXAMPLES
68To set the access and modified times for a new file to those of an
69existing file, use:
70.Bd -literal -offset indent
71struct stat sb;
72const char *existing_filename, *new_filename;
73
74if (stat(existing_filename, &sb) < 0)
75	err(EXIT_FAILURE, "stat failed");
76
77if (elftc_set_timestamps(new_filename, &sb) < 0)
78	err(EXIT_FAILURE, "timestamps could not be set");
