[Mingw-users] Re: Program does not runder when using certain WINVER

[Norman J. <nor...@ar...>]

I checked the mingw/win32api header files against *other* ones and found out
that they seem to be wrong :

typedef struct tagRASCONNA {
    DWORD dwSize;
    HRASCONN hrasconn;
    CHAR szEntryName[RAS_MaxEntryName + 1];
    CHAR szDeviceType[RAS_MaxDeviceType + 1];
    CHAR szDeviceName[RAS_MaxDeviceName + 1];
#if (WINVER >= 0x401)
    CHAR szPhonebook[MAX_PATH];
    DWORD dwSubEntry;
#endif
#if (WINVER >= 0x500)
    GUID guidEntry;
#endif
} RASCONNA, *LPRASCONNA;

has to be

typedef struct tagRASCONNA {
    DWORD dwSize;
    HRASCONN hrasconn;
    CHAR szEntryName[RAS_MaxEntryName + 1];
    CHAR szDeviceType[RAS_MaxDeviceType + 1];
    CHAR szDeviceName[RAS_MaxDeviceName + 1];
#if (WINVER >= 0x400)
    CHAR szDeviceType[ RAS_MaxDeviceType + 1 ];
    CHAR szDeviceName[ RAS_MaxDeviceName + 1 ];
#endif
#if (WINVER >= 0x401)
    CHAR szPhonebook [ MAX_PATH ];
    DWORD dwSubEntry;
#endif
} RASCONNA, *LPRASCONNA;

- otherwise the sizes do not match with the ones that certain functions
expect ! If you want me to create a patch of this
please tell me.

Best regards,

Norman
