_U_DYN_CANCEL(3)	     Programming Library	      _U_DYN_CANCEL(3)

NAME
       _U_dyn_cancel --	cancel unwind-info for dynamically generated code

SYNOPSIS
       #include	<libunwind.h>

       void _U_dyn_cancel(unw_dyn_info_t *di);

DESCRIPTION
       The _U_dyn_cancel() routine cancels the registration of the unwind-info
       for a dynamically generated procedure. Argument di is  the  pointer  to
       the   unw_dyn_info_t  structure	that  describes	 the  procedure's  un-
       wind-info.

       The _U_dyn_cancel() routine is guaranteed to execute in	constant  time
       (in  the	 absence  of contention	from concurrent	calls to _U_dyn_regis-
       ter() or	_U_dyn_cancel()).

THREAD AND SIGNAL SAFETY
       _U_dyn_cancel() is thread-safe but not safe to use from a  signal  han-
       dler.
