示例1: getModuleForAddr
const std::wstring SymbolInfo::getProcForAddr(PROFILER_ADDR addr,
std::wstring& procfilepath_out, int& proclinenum_out)
{
procfilepath_out = L"";
proclinenum_out = 0;
Module *mod = getModuleForAddr(addr);
DbgHelp *dbgHelp = mod ? mod->dbghelp : &dbgHelpMs;
unsigned char buffer[1024];
//blame MS for this abomination of a coding technique
SYMBOL_INFOW* symbol_info = (SYMBOL_INFOW*)buffer;
symbol_info->SizeOfStruct = sizeof(SYMBOL_INFOW);
symbol_info->MaxNameLen = ((sizeof(buffer) - sizeof(SYMBOL_INFOW)) / sizeof(WCHAR)) - 1;
DWORD64 displacement = 0;
BOOL result = dbgHelp->SymFromAddrW(process_handle, (DWORD64)addr, &displacement, symbol_info);
if(!result)
{
DWORD err = GetLastError();
wchar_t buf[256];
#if defined(_WIN64)
if(is64BitProcess)
swprintf(buf, 256, L"[%016llX]", addr);
else
swprintf(buf, 256, L"[%08X]", unsigned __int32(addr));
#else
