36 .Fn acl_get_fd "int fd"
40 function retrieves the access ACL associated with the file referred to by
42 The ACL is placed into working storage and
44 returns a pointer to that storage.
46 In order to read an ACL from an object, a process must have read access to
47 the object's attributes.
49 This function may cause memory to be allocated. The caller should free any

58 On success, this function shall return a pointer to the
59 working storage. On error, a value of
61 shall be returned, and
65 If any of the following conditions occur, the
67 function returns a value of
71 to the corresponding value:
76 argument is not a valid file descriptor.
78 The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management constraints.
80 The file system on which the file identified by
82 is located does not support ACLs, or ACLs are disabled.
