This file helps you do that. // // It does this by defining these functions with the proper signature. // All you need to do is compile this file and the run dumpbin on it. // (See http://msdn.microsoft.com/en-us/library/5x49w699.aspx for more // on dumpbin). To do this in MSVC, use the MSVC commandline shell: // http://msdn.microsoft.com/en-us/library/ms235639(VS.80).aspx) // // The run: // cl /c get_mangled_names.cc // dumpbin /symbols get_mangled_names.obj // // It will print out the mangled (and associated unmangled) names of // the 8 symbols you need to put at the top of patch_functions.cc #include <sys/types.h> // for size_t #include <new> // for nothrow_t static char m; // some dummy memory so new doesn't return NULL. void* operator new(size_t size) { return &m; } void operator delete(void* p) throw() { } void* operator new[](size_t size) { return &m; } void operator delete[](void* p) throw() { } void* operator new(size_t size, const std::nothrow_t&) throw() { return &m; } void operator delete(void* p, const std::nothrow_t&) throw() { } void* operator new[](size_t size, const std::nothrow_t&) throw() { return &m; } void operator delete[](void* p, const std::nothrow_t&) throw() { }
