问CSDK中at_client.c中client_parser()任务不进行阻塞，不会造成任务饥饿么？

物联网设备端开发AT模组中AT线程问题，client_parser()任务不进行阻塞，这样不会造成任务饥饿么？RT-THREAD中就有信号量机制

源码

#ifdef AT_OS_USED

static void client_parser(void *userContex)

{

int resp_buf_len = 0;

const at_urc *urc;

int line_counts = 0;

at_client_t client = at_client_get();

Log_d("client_parser start...");

while (1) {

if (at_recv_readline(client) > 0) {

#ifdef AT_DEBUG

const char *cmd = NULL;

int cmdsize = 0;

cmd = at_get_last_cmd(&cmdsize);

Log_d("last_cmd:(%.*s), readline:%s", cmdsize, STRING_PTR_PRINT_SANITY_CHECK(cmd),

STRING_PTR_PRINT_SANITY_CHECK(client->recv_buffer));

#endif

if ((urc = get_urc_obj(client)) != NULL) {

/* current receive is request, try to execute related operations */

if (urc->func != NULL) {

urc->func(client->recv_buffer, client->cur_recv_len);

}

}
