This pull request adds the
utimensatfunction, which is related tofutimens(already in the code).utimensatallows modifying the mtime/atime using a path instead of a file descriptor, and it also allows modifying mtime/atime on a symlink (the link's inode, rather than the target inode).I also added the two constants which can be passed to
utimensat:AT_FDCWDandAT_SYMLINK_NOFOLLOW. I used http://lxr.free-electrons.com/source/include/uapi/linux/fcntl.h#L56 to get the constant values.I tested
libc::utimensaton my local system (Ubuntu 15.10). Not sure if I'm supposed to add any unit tests with this pull request or not.
