libunwind: libunwind (API to determine the call-chain of a program) libunwind: libunwind: The primary goal of libunwind is to define a portable and efficient C libunwind: programming interface (API) to determine the call-chain of a program. libunwind: The API additionally provides the means to manipulate the preserved libunwind: (callee-saved) state of each call-frame and to resume execution at libunwind: any point in the call-chain (non-local goto). Some uses for this API libunwind: include exception handling, debuggers, introspection, or implementing libunwind: an extremely efficient version of setjmp(). libunwind: libunwind: Homepage: http://www.nongnu.org/libunwind
