Structures

Several new data members were added to DirectPlay structures for DirectX 5.0, and these are supported in the current version. Applications that need to be backward-compatible with older versions of the DirectPlay run-time files should either:

• Use the structures that existed in the DirectX 3.0 header files.
• Check the dwSize member in each structure before attempting to access all members of the structure.

The DirectPlay structures are:

• DPACCOUNTDESC
• DPAPPLICATIONDESC
• DPAPPLICATIONDESC2
• DPCAPS
• DPCHAT
• DPCOMPORTADDRESS
• DPCOMPOUNDADDRESSELEMENT
• DPCREDENTIALS
• DPLAPPINFO
• DPLCONNECTION
• DPNAME
• DPSECURITYDESC
• DPSESSIONDESC2
