NAME

       utimes - set file access and modification times (LEGACY)

SYNOPSIS

       #include <sys/time.h>

       int utimes(const char *path, const struct timeval times[2]);

DESCRIPTION

       The  utimes()  function  shall  set  the access and modification times of the file pointed to by the path
       argument to the value of the times argument. The utimes() function allows time specifications accurate to
       the microsecond.

       For utimes(), the times argument is an array of timeval structures. The first array member represents the
       date and time of last access, and the second member represents the date and time  of  last  modification.
       The  times  in  the  timeval structure are measured in seconds and microseconds since the Epoch, although
       rounding toward the nearest second may occur.

       If the times argument is a null pointer, the access and modification times of the file shall  be  set  to
       the  current  time.  The effective user ID of the process shall match the owner of the file, or has write
       access to the file or appropriate privileges to use this call in this manner. Upon  completion,  utimes()
       shall mark the time of the last file status change, st_ctime, for update.

RETURN VALUE

       Upon  successful  completion, 0 shall be returned. Otherwise, -1 shall be returned and errno shall be set
       to indicate the error, and the file times shall not be affected.

ERRORS

       The utimes() function shall fail if:

       EACCES Search permission is denied by a component of the path prefix; or the times  argument  is  a  null
              pointer  and  the  effective user ID of the process does not match the owner of the file and write
              access is denied.

       ELOOP  A loop exists in symbolic links encountered during resolution of the path argument.

       ENAMETOOLONG
              The length of the path argument  exceeds  {PATH_MAX}  or  a  pathname  component  is  longer  than
              {NAME_MAX}.

       ENOENT A component of path does not name an existing file or path is an empty string.

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

       EPERM  The  times  argument  is  not  a null pointer and the calling process' effective user ID has write
              access to the file but does not match the owner of the file and the calling process does not  have
              the appropriate privileges.

       EROFS  The file system containing the file is read-only.

       The utimes() function may fail if:

       ELOOP  More than {SYMLOOP_MAX} symbolic links were encountered during resolution of the path argument.

       ENAMETOOLONG
              Pathname  resolution  of  a  symbolic  link  produced  an intermediate result whose length exceeds
              {PATH_MAX}.

EXAMPLES

       None.

APPLICATION USAGE

       For applications portability, the utime() function should be used to set  file  access  and  modification
       times instead of utimes().

RATIONALE

       None.

FUTURE DIRECTIONS

       This function may be withdrawn in a future version.
