.Sh NAME

.Nm elftc_set_timestamps
|
|
.Nd set file timestamps
|
|
.Sh LIBRARY

|
|
.Sh SYNOPSIS
|
|
.In libelftc.h
|
|
.Ft int
|
|
.Fn elftc_set_timestamps "const char *filename" "struct stat *sb"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn elftc_set_timestamps
|
|
function is used to set the access and modified time stamps on a file
|
|
based on the contents of a
|
|
.Vt "struct stat"
|
|
descriptor.
|
|
.Pp
|
|
Argument
|
|
.Ar filename
|
|
names an existing file in the file system.
|
|
.Pp
|
|
Argument
|
|
.Ar sb
|
|
points to structure of type
|
|
.Vt "struct stat"
|
|
populated by a prior call to
|
|
.Xr fstat 2
|
|
or
|
|
.Xr stat 2 .
|
|
.Sh IMPLEMENTATION NOTES
|
|
This function will invoke the high-resolution
|
|
.Xr utimes 2
|
|
system call if the underlying operating system supports it.
|
|
On operating systems lacking support for
|
|
.Xr utimes 2 ,
|
|
the function will use lower resolution
|
|
.Xr utime 2
|
|
system call.
|
|
.Sh EXAMPLES
|
|
To set the access and modified times for a new file to those of an
|
|
existing file, use:
|
|
.Bd -literal -offset indent
|
|
struct stat sb;
|
|
const char *existing_filename, *new_filename;
|
|
|
|
if (stat(existing_filename, &sb) < 0)
|
|
err(EXIT_FAILURE, "stat failed");
|
|
|
|
if (elftc_set_timestamps(new_filename, &sb) < 0)
|
|
err(EXIT_FAILURE, "timestamps could not be set");
