#define get_current() (current_thread_info()->task) 可以看出,current调用了current_thread_info函数,此函数的内核路径为:arch/arm/include/asm/thread_info.h,内核版本为2.6.32.65 static inline structthread_info*current_thread_info(void) { register unsigned longspasm("sp"); return(struct thread_inf...
struct thread_info thread_info; #endif unsigned long stack[THREAD_SIZE/sizeof(long)]; }; 当CONFIG_THREAD_INFO_IN_TASK这个配置打开的时候,则thread_union结构中只存在stask成员了。 这时候我们再来看下当thread_info在task_struct结构中时,用一张图描述下。 当thread_info和内核栈是这种关系的时候,内核如...
每个进程在内核中都有一个进程控制块（PCB）来维护进程相关的信息，在Linux下内核的进程控制块就是task_...
task_struct数据结构中的stack成员指向thread_union结构(Linux内核通过thread_union联合体来表示进程的内核栈) 代码语言:javascript 复制 union thread_union{struct thread_info thread_info;unsigned long stack[THREAD_SIZE/sizeof(long)];}; struct thread_info是记录部分进程信息的结构体,其中包括了进程上下文信息: ...
What is Task in C#? .NET framework provides Threading.Tasks class to let you create tasks and run them asynchronously. A task is an object that represents some work that should be done. The task can tell you if the work is completed and if the operation returns a result, the task gives...
