13 \File{\#include $<$libunwind.h$>$}\\
15 \Type{void} \Func{\_U\_dyn\_cancel}(\Type{unw\_dyn\_info\_t~*}\Var{di});\\
19 The \Func{\_U\_dyn\_cancel}() routine cancels the registration of the
20 unwind-info for a dynamically generated procedure. Argument \Var{di}
21 is the pointer to the \Type{unw\_dyn\_info\_t} structure that
22 describes the procedure's unwind-info.
24 The \Func{\_U\_dyn\_cancel}() routine is guaranteed to execute in
25 constant time (in the absence of contention from concurrent calls to
26 \Func{\_U\_dyn\_register}() or \Func{\_U\_dyn\_cancel}()).
29 \section{Thread and Signal Safety}
31 \Func{\_U\_dyn\_cancel}() is thread-safe but \emph{not} safe to use
32 from a signal handler.
