NAME         top

       acl_copy_entry — copy an ACL entry

LIBRARY         top

       Linux Access Control Lists library (libacl, -lacl).

SYNOPSIS         top

       <sys/types.h> <sys/acl.h> int acl_copy_entry(acl_entry_t dest_d,
       acl_entry_t src_d)

DESCRIPTION         top

       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         top

       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         top

       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.
