The exact set of registers stored by \Func{unw\_getcontext}() is platform-specific, but, in general, at least all preserved (``callee-saved'') and all frame-related registers, such as the stack-pointer, will be stored. \section{Return Value} On successful completion, \Func{unw\_getcontext}() returns 0. Otherwise, a value of -1 is returned. \section{Thread and Signal Safety} \Func{unw\_getcontext}() is thread-safe as well as safe to use from a signal handler. \section{See Also} \SeeAlso{libunwind(3)}, \SeeAlso{unw\_init\_local(3)} \section{Author} \noindent David Mosberger-Tang\\ Hewlett-Packard Labs\\ Palo-Alto, CA 94304\\ Email: \Email{davidm@hpl.hp.com}\\ WWW: \URL{http://www.hpl.hp.com/research/linux/libunwind/}. \LatexManEnd \end{document}
