linux 和 ecos 内核线程创建/信号量/event等对比

ecos:

 int gx_thread_create (const char *thread_name, gx_thread_id *thread_id,
         void(*entry_func)(void *), void *arg,
         void *stack_base,
         unsigned int stack_size,
         unsigned int priority,
         gx_thread_info *thread_info)
 {
 #define GX_THREAD_PRIORITY_MAX  255

     if (priority > GX_THREAD_PRIORITY_MAX || thread_id == NULL \
             || entry_func == NULL || thread_name == NULL \
             || stack_base == NULL || thread_info == NULL)
         return -; 

     cyg_thread_create_ex((cyg_addrword_t)priority, (cyg_thread_entry_t *)entry_func, (cyg_addrword_t)arg,
             (char *)thread_name, stack_base, (cyg_ucount32)stack_size, thread_id, thread_info, ); 

     cyg_thread_resume(*thread_id);

     return ;
 }

linux：

 int gx_thread_create (const char *thread_name, gx_thread_id *thread_id,
         void(*entry_func)(void *), void *arg,
         void *stack_base,
         unsigned int stack_size,
         unsigned int priority,
         gx_thread_info *thread_info)
 {
     struct task_struct *task = NULL;

     task = kthread_create((int (*)(void *))entry_func, arg, "%s",thread_name);
     if(task == NULL)
         return -; 

     GXAV_DBG("%s(),task : %p\n",__func__,task);

     *thread_id = (unsigned int)task;

     GXAV_DBG("%s(),thread_id : 0x%x\n",__func__,*thread_id);

     wake_up_process(task);

     return ;
 }
