Get file size error

[LoveChina-3000]

In line 879 code，On 32-bite ，Get file size error，I modified part of the code 。

inline unsigned __int64 query_file_size(file_handle_type handle, std::error_code& error) { error.clear(); #ifdef _WIN32 // LARGE_INTEGER file_size; // if(::GetFileSizeEx(handle, &file_size) == 0) // { // error = detail::last_error(); // return 0; // } //return static_cast<int64_t>(file_size.QuadPart);

DWORD dwFileSizeHigh;
__int64 qwFileSize = GetFileSize(handle, &dwFileSizeHigh);
qwFileSize += (((_int64)dwFileSizeHigh) << 32);
return qwFileSize;

#else // POSIX struct stat sbuf; if(::fstat(handle, &sbuf) == -1) { error = detail::last_error(); return 0; } return sbuf.st_size; #endif }
