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
       unwind-info.

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

THREAD AND SIGNAL SAFETY

       _U_dyn_cancel() is thread-safe but not safe to use from a signal handler.
