UTIMES(2)                 OpenBSD Programmer's Manual                UTIMES(2)

NAME
     utimes - set file access and modification times



SYNOPSIS
     #include <sys/time.h>

     int
     utimes(const char *file, const struct timeval *times);

     int
     futimes(int fd, const struct timeval *times);

DESCRIPTION
     The access and modification times of the file named by path or referenced
     by fd are changed as specified by the argument times.

     If times is NULL, the access and modification times are set to the cur-
     rent time.  The caller must be the owner of the file, have permission to
     write the file, or be the super-user.

     If times is non-null, it is assumed to point to an array of two timeval
     structures.  The access time is set to the value of the first element,
     and the modification time is set to the value of the second element.  The
     caller 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
     utimes() will fail if:

     [EACCES]      Search permission is denied for a component of the path
                   prefix; or the times argument is NULL and the effective us-
                   er 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 ad-
                   dress space.

     [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 {NAME_MAX} characters,
                   or an entire path name exceeded {PATH_MAX} 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.

     futimes() will fail if:

     [EBADF]       fd does not refer to a valid descriptor.

     [EACCES]      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]      times points outside the process's allocated address space.

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

     [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.
