+\end{Name}

+\section{Synopsis}
+
+\File{\#include $<$libunwind.h$>$}\\
+
+\Type{int} \Func{unw\_get\_reg}(\Type{unw\_cursor\_t~*}\Var{cp}, \Type{unw\_regnum\_t} \Var{reg}, \Type{unw\_word\_t~*}\Var{valp});\\
+
+\section{Description}
+
+The \Func{unw\_get\_reg}() routine reads the value of register
+\Var{reg} in the stack frame identified by cursor \Var{cp} and stores
+the value in the word pointed to by \Var{valp}.
+
+The register numbering is target-dependent and described in separate
+manual pages (e.g., libunwind-ia64(3) for the IA-64 target).
+Furthermore, the exact set of accessible registers may depend on the
+type of frame that \Var{cp} is referring to.  For ordinary stack
+frames, it is normally possible to access only the preserved
+(``callee-saved'') registers and frame-related registers (such as the
+stack-pointer).  However, for signal frames (see
+\Func{unw\_is\_signal\_frame}(3)), it is usually possible to access
+all registers.
+
+Note that \Func{unw\_get\_reg}() can only read the contents of
+registers whose values fit in a single word.  See
+\Func{unw\_get\_fpreg}(3) for a way to read registers which do not fit
+this constraint.
+
+\section{Return Value}
+
+On successful completion, \Func{unw\_get\_reg}() returns 0.
+Otherwise the negative value of one of the error-codes below is
+returned.
+
+\section{Thread and Signal Safety}
+
+\Func{unw\_get\_reg}() is thread-safe as well as safe to use
+from a signal handler.
+
+\section{Errors}
+
+\begin{Description}
+\item[\Const{UNW\_EUNSPEC}] An unspecified error occurred.
+\item[\Const{UNW\_EBADREG}] An attempt was made to read a register
+  that is either invalid or not accessible in the current frame.
+\end{Description}
+In addition, \Func{unw\_get\_reg}() may return any error returned by
+the \Func{access\_mem}(), \Func{access\_reg}(), and
+\Func{access\_fpreg}() call-backs (see
+\Func{unw\_create\_addr\_space}(3)).
