\begin{Name}{3}{unw\_apply\_reg\_state}{David Mosberger-Tang}{Programming Library}{unw\_apply\_reg\_state}unw\_apply\_reg\_state -- apply a register state update to a cursor
\end{Name}
\section{Synopsis}
\File{\#include $<$libunwind.h$>$}\\
\Type{int}
\Func{unw\_apply\_reg\_state}(\Type{unw\_cursor\_t~*}\Var{cp},
\Type{void~*}\Var{reg\_states\_data});\\
\section{Description}
The \Func{unw\_apply\_reg\_state}() routine updates the register values
of a cursor according to the instructions in \Var{reg\_states\_data},
which have been obtained by calling \Var{unw\_reg\_states\_iterate}.
\section{Return Value}
On successful completion, \Func{unw\_apply\_reg\_state}() returns 0.
Otherwise the negative value of one of the error-codes below is
returned.
\section{Thread and Signal Safety}
\Func{unw\_apply\_reg\_state}() is thread-safe. If cursor \Var{cp} is
in the local address-space, this routine is also safe to use from a
signal handler.
\section{Errors}
\begin{Description}
\item[\Const{UNW\_EUNSPEC}] An unspecified error occurred.
\item[\Const{UNW\_ENOINFO}] \Prog{Libunwind} was unable to locate
unwind-info for the procedure.
\item[\Const{UNW\_EBADVERSION}] The unwind-info for the procedure has
version or format that is not understood by \Prog{libunwind}.
\end{Description}
In addition, \Func{unw\_apply\_reg\_state}() may return any error
returned by the \Func{access\_mem}() call-back (see
\Func{unw\_create\_addr\_space}(3)).
