UTIME(3) FreeBSD Library Functions Manual UTIME(3)
NAME utime - set file times
LIBRARY Standard C Library (libc, -lc)
SYNOPSIS #include <utime.h>
int utime(const char *file, const struct utimbuf *timep);
DESCRIPTION This interface is obsoleted by utimensat(2) because it is not accurate to fractions of a second.
The utime() function sets the access and modification times of the named file from the actime and modtime fields of the struct utimbuf pointed at by timep.
If the times are specified (the timep argument is non-NULL) the caller must be the owner of the file or be the super-user.
If the times are not specified (the timep argument is NULL) the caller must be the owner of the file, have permission to write the file, or be the super-user.
ERRORS The utime() function may fail and set errno for any of the errors specified for the library function utimes(2).
SEE ALSO stat(2), utimensat(2), utimes(2)
STANDARDS The utime() function conforms to IEEE Std 1003.1-1988 ("POSIX.1").
HISTORY A utime() function appeared in Version 7 AT&T UNIX.
