你知道为什么某些文件没有被这个程序列出,即使它们是“常规的”?:
#include <stdio.h>
#include <sys/types.h>
#include <sys/param.h>
#include <sys/stat.h>
#include <dirent.h>
int main(void) {
DIR *dh = opendir("./"); // directory handle
struct dirent *file; // a 'directory entity' AKA file
struct stat info; // info about the file.
while (file = readdir(dh)) {
stat(file->d_name, &info);
printf("note: file->d_name => %s\n", file->d_name);
printf("note: info.st_mode => %i\n", info.st_mode);
if (S_ISREG(info.st_mode))
printf("REGULAR FILE FOUND! %s\n", file->d_name);
}
closedir(dh);
return 0;
}
执行此程序后,我得到以下信息:
note: file->d_name => .
note: info.st_mode => 16877
note: file->d_name => ..
note: info.st_mode => 16832
note: file->d_name => .DS_Store
note: info.st_mode => 16832
note: file->d_name => ef efeff
note: info.st_mode => 16832
note: file->d_name => ffffff
note: info.st_mode => 16832
note: file->d_name => ffffff - copie
note: info.st_mode => 16832
note: file->d_name => folder
note: info.st_mode => 16832
note: file->d_name => printiie.tt
note: info.st_mode => 16832
note: file->d_name => test.c
note: info.st_mode => 33188
REGULAR FILE FOUND! test.c
note: file->d_name => z
note: info.st_mode => 33188
REGULAR FILE FOUND! z
如您所见,程序看到的只有两个文件。但是每个文件都是有规律的,而且只有一个文件夹。
这是shell命令的副本$ ls -lai

我只想列出每个文件的名称,但没有目录。我在 Mac OS X 上工作,但我不认为这可能是问题的原因。
