\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)).
