optee CA和TA 例程 - 值传递

CA

如下实现一个简单的CA代码示例，它使用了不同的Params类型

#include <err.h>
#include <stdio.h>
#include <string.h>
#include <stdlib.h>

/* OP-TEE TEE client API (built by optee_client) */
#include <tee_client_api.h>

/* To the the UUID (found the the TA's h-file(s)) */
#include <hello_world_ta.h>

#define CMD_TEST_VALUE  0x001 
#define CMD_TEST_BUFFER 0x002
#define TA_HELLO_WORLD_UUID  {
      0xc02ffd4f, 0xa7a3, 0xb1c3,
									{
    0x92, 0x08, 0x37, 0x06, 0xe4, 0xc8, 0xb1, 0xaf } }
int main(int argc ,char **argv)
{
   
        TEEC_Result res;
        TEEC_Context ctx;
        TEEC_Session sess;
        TEEC_Operation op;
        TEEC_UUID uuid = TA_HELLO_WORLD_UUID;
        uint32_t err_origin;

        /* Initialize a context connecting us to the TEE */
        res = TEEC_InitializeContext(NULL<
