Writing "find" code
I've got a project that writing "find" code in solaris.
That is finding a file in current and sub directories. While I am looking for some example on the book for two days, but I have no idea where to start. I think I need to use recursion, but is it true? I am still a Unix beginner and the teacher and book didn't give me enough info... Please tell me the way of structure and concept. Thanks in advance.

>Thanks anyway. Did you even look at the man page? It gives you a suite of C functions for reading and traversing directories. With those you can easily devise a recursive function to do what you want.

It says plenty, you just aren't reading into it enough. You'll find that the man pages contain pretty much everything you'll need for most situations. For example, by reading the man pages for opendir, readdir and closedir, I could come up with this to test their functionality:
Code:
#include <dirent.h>
#include <stdio.h>
int main(void)
{
DIR *d;
struct dirent *dir;
if ((d = opendir(".")) != NULL) {
while ((dir = readdir(d)) != NULL)
printf("%s\n", dir->d_name);
closedir(d);
}
return 0;
}
