[VC++] VC++ 6.0 中 DWORD_PTR 这些东东

编译一个程序，发现报告

error C2501: 'DWORD_PTR' : missing storage-class or type specifiers

DWORD_PTR
Unsigned long type for pointer precision. Use when casting a pointer to a long type to perform pointer arithmetic. (Also commonly used for general 32-bit parameters that have been extended to 64 bits in 64-bit Windows. )

想起还没有装 SP6，安装了之后，没有这个问题了，不过我看看资料，加上这些也可以

typedef long LONG_PTR;
typedef unsigned long ULONG_PTR;
typedef ULONG_PTR DWORD_PTR;
