\section{Description}
|
||||
|
||||
The \Func{unw\_get\_fpreg}() routine reads the value of floating-point
|
||||
register \Var{reg} in the stack frame identified by cursor \Var{cp}
|
||||
and stores the value in the variable 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\_fpreg}() can only read the contents of
|
||||
floating-point registers. See \Func{unw\_get\_fpreg}(3) for a way to
|
||||
read registers which fit in a single word.
|
||||
|
||||
\section{Return Value}
|
||||
|
||||
On successful completion, \Func{unw\_get\_fpreg}() returns 0.
|
||||
Otherwise the negative value of one of the error-codes below is
|
||||
returned.

\section{Description}
|
||||
|
||||
The \Func{unw\_is\_signal\_frame}() routine returns a positive value
|
||||
if the current frame identified by \Var{cp} is a signal frame, and a
|
||||
value of 0 otherwise. For the purpose of this discussion, a signal
|
||||
frame is a frame that was created in response to a potentially
|
||||
asynchronous interruption. For UNIX and UNIX-like platforms, such
|
||||
frames are normally created by the kernel when delivering a signal.
|
||||
In a kernel-environment, a signal frame might, for example, correspond
|
||||
to a frame created in response to a device interrupt.
|
||||
|
||||
Signal frames are somewhat unusual because the asynchronous nature of
|
||||
the events that create them require storing the contents of registers
|
||||
that are normally treated as scratch (``caller-saved'') registers.
|
||||
|
||||
\section{Return Value}
|
||||
|
||||
On successful completion, \Func{unw\_is\_signal\_frame}() returns a
|
||||
positive value if the current frame is a signal frame, or 0 if it is
|
||||
not. Otherwise, a negative value of one of the error-codes below is

\Func{unw\_set\_reg}() is thread-safe as well as safe to use

\section{Errors}
|
||||
|
||||
\begin{Description}
|
||||
\item[\Const{UNW\_EUNSPEC}] An unspecified error occurred.
|
||||
\item[\Const{UNW\_EBADREG}] An attempt was made to write a register
|
||||
that is either invalid or not accessible in the current frame.
|
||||
\item[\Const{UNW\_EREADONLY}] An attempt was made to write to a
|
||||
read-only register.
|
||||
\end{Description}
|
||||
In addition, \Func{unw\_set\_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)).

\section{Synopsis}
|
||||
|
||||
\File{\#include $<$libunwind.h$>$}\\
|
||||
|
||||
\Type{int} \Func{unw\_step}(\Type{unw\_cursor\_t~*}\Var{cp});\\
|
||||
|
||||
\section{Description}
|
||||
|
||||
The \Func{unw\_step}() routine advances the unwind cursor \Var{cp} to
|
||||
the next older, less deeply nested stack frame.
|
||||
|
||||
\section{Return Value}
|
||||
|
||||
On successful completion, \Func{unw\_step}() returns a positive value
|
||||
if there are more stack frames in the call-chain, or 0 if the returned
|
||||
stack frame is the last frame in the chain. On error, the negative
|
||||
value of one of the error-codes below is returned.
|
||||
|
||||
\section{Thread and Signal Safety}
|
||||
|
||||
\Func{unw\_step}() 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\_ENOINFO}] \Prog{Libunwind} was unable to locate the
|
||||
unwind-info needed to complete the operation.
|
||||
\item[\Const{UNW\_EBADVERSION}] The unwind-info needed to complete the
|
||||
operation has a version or a format that is not understood by
|
||||
\Prog{libunwind}.
|
||||
\item[\Const{UNW\_EINVALIDIP}] The instruction-pointer
|
||||
(``program-counter'') of the next stack frame is invalid (e.g., not
|
||||
properly aligned).
|
||||
\item[\Const{UNW\_EBADFRAME}] The next stack frame is invalid.
|
||||
\item[\Const{UNW\_ESTOPUNWIND}] Returned if a call to
|
||||
\Func{find\_proc\_info}() returned -\Const{UNW\_ESTOPUNWIND}.
|
||||
\end{Description}
|
||||
In addition, \Func{unw\_step}() may return any error returned by the
|
||||
\Func{find\_proc\_info}(), \Func{get\_dyn\_info\_list\_addr}(),
|
||||
\Func{access\_mem}(), \Func{access\_reg}(), or \Func{access\_fpreg}()
|
||||
call-backs (see \Func{unw\_create\_addr\_space}(3)).
