Detailed Description

The TEEC_SharedMemory structure is used to contain control information related to a block of shared memory that is mapped between the client and the service.

Member Data Documentation

uint32_t TEEC_SharedMemory::allocated

Shared memory type

void* TEEC_SharedMemory::buffer

The pointer to the block of shared memory.

TEEC_Context* TEEC_SharedMemory::context

Implementation defined fields.

Device context

uint32_t TEEC_SharedMemory::flags

flags is a bit-vector which can contain the following flags:
TEEC_MEM_INPUT: the memory can be used to transfer data from the Client Application to the TEE.
TEEC_MEM_OUTPUT: The memory can be used to transfer data from the TEE to the Client Application.
All other bits in this field SHOULD be set to zero, and are reserved for future use.

struct list TEEC_SharedMemory::head_ref

List head used by Context

int TEEC_SharedMemory::operation_count

Operation count

int TEEC_SharedMemory::s_errno

Service error number

size_t TEEC_SharedMemory::size

The length of the shared memory block in bytes. Should not be zero
