Linux: 文档 :相关接口文档手册还是需要仔细阅读
接口文档的阅读，一定要仔细。最近遇到一个问题，明明文档里有说，read函数读取到的是一个或者多个events，但是代码里依然按照一个来处理。就会导致漏event的可能。漏了event，后续的逻辑就会受影响。
Each successful read(2) returns a buffer containing one or more of the following
structures:
struct inotify_event {
int wd; /* Watch descriptor */
uint32_t mask; /* Mask describing event */
uint32_t cookie; /* Unique cookie associating related
events (for rename(2)) */
uint32_t len; /* Size of name field */
char name[]; /* Optional null-terminated name */
};
wd identifies the watch for which this event occurs. It is one of the watch descriptors returned by a previous call to inotify_add_watch(2).
这种读文档不仔细的例子，之前还碰到过一两次。有可能大家只是用，从来不读帮助手册，这是不可取的。
