你最好的赌注可能是""http://linux.die.net/man/3/glob" rel="nofollow">glob(3) 。它几乎就是你想要的。您所说的正确代码的草图就是这个。

glob_t glob_result;
snprintf(glob_pattern, PATH_MAX, "%s/%s", directory, file_pattern);
glob(glob_pattern, 0, NULL, &glob_result);
for (size_t i = 0; i < glob_result.gl_pathc; ++i) {
  char *path = glob_result.gl_pathv[i];
  /* process path */
}
