_U_DYN_CANCEL(3libunwind)    Programming Library     _U_DYN_CANCEL(3libunwind)

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.
