NAME
     acl_copy_entry - copy an ACL entry
LIBRARY
     Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
     #include <sys/types.h>
     #include <sys/acl.h>
     int
     acl_copy_entry(acl_entry_t dest_d, acl_entry_t src_d);
DESCRIPTION
     The acl_copy_entry() function copies the contents of the ACL entry
     indicated by the src_d descriptor to the existing ACL entry indicated by
     the dest_d descriptor. The src_d and dest_d descriptors may refer to
     entries in different ACLs.
RETURN VALUE
     The acl_copy_entry() function returns the value 0 if successful;
     otherwise the value -1 is returned and the global variable errno is set
     to indicate the error.
ERRORS
     If any of the following conditions occur, the acl_copy_entry() function
     returns -1 and sets errno to the corresponding value:
     [EINVAL]           The argument src_d or dest_d is not a valid descriptor
                        for an ACL entry.
                        The arguments src_d and dest_d reference the same ACL
                        entry.
