UTIME(3C)																 UTIME(3C)

NAME

       utime - set file times

SYNOPSIS

       #include <sys/types.h>

       utime(file, timep)
       char *file;
       time_t timep[2];

DESCRIPTION

       This interface is obsoleted by utimes(2).

       The  utime  call  uses  the  `accessed' and `updated' times in that order from the timep vector to set the corresponding recorded times for
       file.

       The caller must be the owner of the file or the super-user.  The `inode-changed' time of the file is set to the current time.

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 utimes(2).

     The utime() function sets the access and modification times of the named file.

     If timep is NULL, the access and modification times are set to the current time.  The calling process must be the owner of the file or have
     permission to write the file.

     If timep is non-NULL, time is assumed to be a pointer to a utimbuf structure, as defined in <utime.h>:

	   struct utimbuf {
		   time_t actime;	   /* Access time */
		   time_t modtime;	   /* Modification time */
	   };

     The access time is set to the value of the actime member, and the modification time is set to the value of the modtime member.  The times are
     measured in seconds since 0 hours, 0 minutes, 0 seconds, January 1, 1970 Coordinated Universal Time (UTC).  The calling process must be the
     owner of the file or be the super-user.

     In either case, the inode-change-time of the file is set to the current time.

RETURN VALUES

     Upon successful completion, a value of 0 is returned.  Otherwise, a value of -1 is returned and errno is set to indicate the error.

ERRORS

     utime() will fail if:

     [EACCES]		Search permission is denied for a component of the path prefix; or the times argument is NULL and the effective user ID of
			the process does not match the owner of the file, and is not the super-user, and write access is denied.

     [EFAULT]		file or times points outside the process's allocated address space.

     [EINVAL]		The pathname contains a character with the high-order bit set.

     [EIO]		An I/O error occurred while reading or writing the affected inode.

     [ELOOP]		Too many symbolic links were encountered in translating the pathname.

     [ENAMETOOLONG]	A component of a pathname exceeded 255 characters, or an entire path name exceeded 1023 characters.

     [ENOENT]		The named file does not exist.

     [ENOTDIR]		A component of the path prefix is not a directory.

     [EPERM]		The times argument is not NULL and the calling process's effective user ID does not match the owner of the file and is not
			the super-user.

     [EROFS]		The file system containing the file is mounted read-only.

STANDARDS

     The utime() function conforms to ISO/IEC 9945-1:1990 (``POSIX.1'').  It was however marked as legacy in the IEEE Std 1003.1-2008
     (``POSIX.1'') revision of the standard.

HISTORY

     A utime() function appeared in Version 7 AT&T UNIX.
