Glob函数(c)和备份文件(file~)
我正在使用 glob 函数作为自动完成函数。我向您展示这个问题是因为它很难解释：
matched = ~/.tcsh
glob(matched, 0, NULL, &pglob);
glob 将所有匹配的文件放入一个 char ** 中，当我打印它时，我有：
case[0] = .tcshrc
case[1] =
我应该有 .tcshrc~ in case[1]，但什么也没有=S，我见过这样的标志“GLOB_TILDE”“
glob(matched, GLOB_TILDE, NULL, &pglob);
但它不会改变任何东西！有人可以帮助我吗？
I'm using glob function for a autocompletion function. I'm showing you the problem because it's difficult to explain:
matched = ~/.tcsh
glob(matched, 0, NULL, &pglob);
glob put all matched files in a char ** and when I print it I have:
case[0] = .tcshrc
case[1] =
I should have .tcshrc~ in case[1], but nothing =S, I've seen a flag "GLOB_TILDE" like this "
glob(matched, GLOB_TILDE, NULL, &pglob);
But it doesn't change anything! Can someone help me?

GLOB_TILDE 标志仅在 ~ 出现在 glob 开头时影响输出。请参阅此处：

至于你的问题，在我看来你的匹配值是错误的。似乎您应该在其末尾添加一个
*，这样它对于自动完成很有用，即：我对您之前的示例如何找到第一个示例感到有点困惑。这篇手册页文章的底部也有一些有趣的示例：

The
GLOB_TILDEflag only affects the output when the ~ appears at the beginning of the glob. See here:http://www.gnu.org/s/libc/manual/html_node/More-Flags-for-Globbing.html
As for your problem, it appears to me that your matched value is wrong. Seems like you should be sticking a
*at the end of it for it to be useful for autocompletion, i.e.:I'm a little bit confused as how your previous example found even the first one. The bottom part of this man page article has some interesting examples too:
