Though recursion is allowed for epoch-protected sections, +recursive calls will be associated with the +.Fn ck_epoch_begin 3 +that is at the top of the call stack. If a section is passed, then +recursion on a record will cause the epoch to be refreshed on entry +of every protected section. +.Sh RETURN VALUES +This function has no return value. +.Sh ERRORS +The object pointed to by +.Fa epoch +must have been previously initiated via +.Fn ck_epoch_init 3 . +The object pointed to by +.Fa record +must have been previously registered via +.Fn ck_epoch_register 3 . +.Sh SEE ALSO +.Xr ck_epoch_init 3 , +.Xr ck_epoch_register 3 , +.Xr ck_epoch_unregister 3 , +.Xr ck_epoch_recycle 3 , +.Xr ck_epoch_poll 3 , +.Xr ck_epoch_synchronize 3 , +.Xr ck_epoch_reclaim 3 , +.Xr ck_epoch_barrier 3 , +.Xr ck_epoch_call 3 , +.Xr ck_epoch_end 3 +.Pp +Additional information available at http://concurrencykit.org/ |
