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



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

SYNOPSIS
       #include <sys/types.h>
       #include <utime.h>

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


       #include <sys/time.h>

       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 appropri-
       ately.

ERRORS
       Other errors may occur.


       EACCES Permission to write the file is denied.

       ENOENT filename does not exist.
