What is the C function is used to search for files in the directory or subdirectory? Theare is a function ' stat ' for which if you give the file name we can get the information about that file whether it is ordinary file or a directory etc. Like this is there any function which searchs for the files in the directory?

1.  What operating system are you using?
2.  What exactly do you mean by "search"?  Determining if a filename exists?  Listing all files that meet certain criteria?  Listing all files in a given directory?

Use opendir to open the directory structur and readdir to read ony entry. with stat (fstat) you can check the type of the entry (file or subdir).

DIR *pdir
struct dirent *pentry;
struct stat stat;

pdir=opendir ("/");
while (NULL != (pentry = readdir (pdir))) {
      stat (pdir->d_name,&stat);
      if (stat.st_mode & S_IFDIR) {
            printf ("Directory: %s",pdir->d_name);
      }
}

I am sorry, If I am not clear in the question. The question is like this. If I give a pattern say
' *.* ', it should list all the file names in the current directory and the sub-directories. Like in windows sdk programming we have FindFirstFile and FineNextFile which helps for doing the above. Same way is there any functions in C language. Actually I want write for both dos and unix. That is why I am using only C functions.

Thank you.

Preface I don't like visual development tools that are supposed to write a program for me. Even if it is Xcode and I can use Interface Builder. Yes, it is a perfect tool and has helped me a lot, mainly, in the beginning, when my programs were small…
This is a short and sweet, but (hopefully) to the point article. There seems to be some fundamental misunderstanding about the function prototype for the "main" function in C and C++, more specifically what type this function should return. I see so…
