@ -37,6 +37,14 @@ contents of that register. In other words, the exception handling
arguments are installed even in cases where normally only the
``preserved'' registers are restored.
Note that \Func{unw\_resume}() does \emph{not} invoke any unwind
handlers (aka, ``personality routines''). If a program needs this, it
will have to do so on its own by obtaining the \Type{unw\_proc\_info\_t}
of each unwound frame and appropriately processing its unwind handler
and language-specific data area (lsda). These steps are generally
dependent on the target-platform and are regulated by the
processor-specific ABI (application-binary interface).
\section{Return Value}
For local unwinding, \Func{unw\_resume}() does not return on success.
