Buffer descriptor X copies memory into a "pointer buffer" that the IPC server specifies to the kernel by preparing a message with a C descriptor pointing to the pointer buffer before calling svcReplyAndReceive. Addresses in the X descriptors are transmuted to point into the pointer buffer, and if data doesn't fit in the pointer buffer, 0xce01 is returned back to the client. | |||
