Configures an optional, custom pointer-sized context value with this local chat user object.

Syntax

Parameters

customContext   void*
optional
An arbitrary, pointer-sized value to store with the chat user object.

Return value

PartyError c_partyErrorSuccess if configuring the custom context succeeded or an error code otherwise. The human-readable form of the error code can be retrieved via PartyXblManager::GetErrorMessage().

Remarks

The custom context is typically used as a “shortcut” that simplifies accessing local, title-specific memory associated with the chat user without requiring a mapping lookup. The value is retrieved using the GetCustomContext() method.

Any configured value is treated as opaque by the library, and is only valid on the local device; it is not transmitted over the network.
