/* Set the access control lists of a file to match *exactly* MODE (this might
|

remove inherited ACLs). Note chmod() tends to honor inherited/default
|
|
ACLs. If DESC is a valid file descriptor, use file descriptor operations
|
|
where available, else use filename based operations on NAME. If access
|
|
control lists are not available, fchmod the target file to MODE. Also
|
|
sets the non-permission bits of the destination file
|
|
(S_ISUID, S_ISGID, S_ISVTX) to those from MODE if any are set.
|
|
Return 0 if successful. Return -1 and set errno upon failure. */
