H A Dcredentials.rst213 在Linux中，一个任务的所有凭据都保存在一个引用计数结构体‘struct cred’中，
215 task_struct中通过一个名为‘cred’的指针指向其凭据。
232 要更改cred结构体中的任何内容，必须遵循复制和替换的原则。首先进行复制，然后修
264 const struct cred *current_cred()
290 const struct cred *get_current_cred(void);
292 以及用于获取对一个实际上不存在于struct cred中的凭据的引用的函数::
311 const struct cred *__task_cred(struct task_struct *task);
317 const struct cred *tcred;
331 const struct cred *get_task_cred(struct task_struct *task);
358 这里的‘member’是cred结构体的非指针成员。例如::
