H A Derrseq.rst16 errseq_t数据类型
19 ``errseq_t`` 是一种在一个地方记录错误的方法，并允许任意数量的 ``订阅者`` 判断自上
41 总体思路是让 ``观察者`` 对errseq_t值进行采样，并将其保留为运行游标。该值稍后可用
45 新的errseq_t应始终清零。全零的errseq_t值是从未出现错误的特殊（但常见）情况。因此，
65 errseq_t wd_err; /* 用来记录错误 */
72 wd.wd_err = (errseq_t)0;
78 errseq_t s_wd_err; /* wd_err的私有“游标” */
110 他只需对员工当前的errseq_t进行采样，然后用它来判断后来是否发生了错误::
112 errseq_t since = errseq_sample(&wd.wd_err);
119 序列化更新errseq_t游标
