Directory travesal program
 

Hi,

Has anyone have any idea how to write a program to traverse thru a directory? I tried but had a false start. I can't even open a directory with "opendir" command to begin with. Is that something to do with permission? But I think I have read, write and execution right for that directory. I'm so totally clueless...

Thanks

What language are you talking about using

Are you sure it is a directory you are trying to open? opendir returns null if the name is not a directory, but it may be a file. In the case that it may be a file you need to use the "readdir" function on the directory that contains the file, or current directory, this returns a " struct dirent* ". Successive calls to readdir return the next file in the directory, when the end is reached readdir returns NULL. You use the function "stat" to find out information about the file. The functions "getpwuid"and "getgrgid" return the user id and group id of the owner fo the file. And yes read permissions are needed on the directory.

Hope this helps

just do a system call "system("cd /dir");"
