i keep getting an error saying that d_type is not a valid member of struct dirent, but isn't this meant to be the field that contains whether the object found is a file or a folder. i am using Dev-C++ 4 here is the code:

Quote:

#include <stdio.h>
#include <unistd.h>
#include <dirent.h>

int main(int argc, char *argv[])
{
int numfiles=0;
DIR *dir;
struct dirent *read_dir;
dir=opendir("C:\\");
read_dir=readdir(dir);
if (dir != NULL)
{
while (read_dir = readdir (dir))
puts (read_dir->d_name);
(void) closedir (dir);
if(read_dir->d_type==DT_DIR)
{
}
}
else
puts ("Couldn't open the directory.");
getch();
return 0;
}

sorry just checked the header file(dirent.h) this d_type data field doesn't even exist can any body recommend any way to check if what is found is a file or a folder. I thank you in advanced for your replies.

Use the stat function on the file name that is found and check

(Toggle Plain Text)

(StatBuffer.st_mode & S_IFDIR) != 0

Just a tip. "quote" tags don't preserve your indentation, "code" tags do. Thanks for trying, though.
