stat system calls

[CaptRage61]

Does anyone know how to use the Stat system calls to check if a file is a directory or just a file? I checked the man page and I found that you need to use S_ISDIR(m) but it does not say how to use it, does anyone know?

Yes. Use the macro against the st_mode member.

What would that look like?
I have :

DIR* d;
struct dirent *dirPointer;

dirPointer = readdir ( d );

How would I check to see if dirPointer is a directory or not using the stat commands??

Something like

struct stat sb;
struct dirent *dirPointer;

dirPointer = readdir ( d );      /* read a dir entry */
stat( dirPointer->d_name, &sb ); /* stat it */

if ( S_ISDIR( sb.st_mode ) ) {
  /* do something with the directory */
}
