C语言 扫描以. word结尾的目录中的所有文件

Question

我正试图写一个c代码来扫描以.wor结尾的文件的整个目录，打开每个文件并从中提取某些信息。
到目前为止，我的代码成功打开了该目录下的所有文件，并扫描它们以寻找目标单词。我是否有办法修改代码，以便它只扫描以。word结尾的文件?我已经尝试了通配符"*"。但它只是给了我一个错误，说符号*和。Wor不被识别。
非常感谢您的帮助!
(顺便说一句，我无法得到我在结束时添加的计数器工作，我试图使用整数"c"来增加每次读取文件，并显示在结束时读取的文件总数。它现在给我的是0

下面是我的代码:

您可以手动检查每个文件名是否以.wor结尾，如下所示:

size_t len = strlen(in_file->d_name);
if (len >= 4 && memcmp(in_file->d_name + len - 4, ".wor", 4) == 0)
{
    // The filename ends in ".wor" (case-sensitive).  Note that this also
    // accepts the file whose entire name is ".wor".
}

或者，您可以使用glob(3)函数来获取匹配特定通配符的文件名列表:

// Error checking omitted for expository purposes
glob_t globbuf;
glob("/home/iselabs/dwang/pinscale/workorder/practice/*.wor", 0, NULL, &globbuf);
for (size_t i = 0; i < globbuf.gl_pathc; i++)
{
    char *filename = globbuf.gl_pathv[i];
    // Process filename...
}
globfree(&globbuf);
