File last modification time的意思|示意

For example, the directory in Listing 1 shows that the foo.o object is older than the last modification time of the corresponding foo.c source file.

例如，清单1中的目录表明，foo . o对象比相应的foo . c源文件的最后修改日期更新。

The read_file function USES the stat function call to check the modification time of the file, only re-reading the contents of the file if it changed since the last time the file was loaded.

read _ file函数使用stat函数调用检查文件的修改时间，只有在上一次装载之后修改了文件的情况下，它才重新读取文件的内容。
