UTIME(2)		  Linux Programmer's Manual		     UTIME(2)



NAME
       utime, utimes - change access and/or modification times of an inode

SYNOPSIS
       #include 
       #include 

       int utime(const char *filename, const struct utimbuf *buf);


       #include 

       int utimes(char *filename, struct timeval *tvp);

DESCRIPTION
       utime changes the access and modification times of the inode specified
       by filename to the actime and modtime fields of buf respectively.   If
       buf  is	NULL,  then the access and modification times of the file are
       set to the current time.	 The utimbuf structure is:

	      struct utimbuf {
		      time_t actime;  /* access time */
		      time_t modtime; /* modification time */
	      };

       In the Linux DLL 4.4.1 libraries, utimes is just a wrapper for  utime:
       tvp[0].tv_sec  is  actime,  and tvp[1].tv_sec is modtime.  The timeval
       structure is:

	      struct timeval {
		      long    tv_sec;	      /* seconds */
		      long    tv_usec;	      /* microseconds */
	      };

RETURN VALUE
       On success, zero is returned.  On error, -1 is returned, and errno  is
       set appropriately.

ERRORS
       Other errors may occur.


       EACCES Permission to write the file is denied.

       ENOENT filename does not exist.
