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.
