The following works fine for me. Add your own headers and ignore the Strtab
struct, it's a local thing of the proggy. Same goes for the functions
warning() and addstrtab().

/* read all entries from current dir */
#include "cptree.h"
void readentries (Strtab *tab, char *dirname)
{
 DIR *d;
 struct dirent *dent;

 if (! (d = opendir (".")) )
 {
	warning ("cannot read directory entries in %s", dirname);
	return;
 }

 while ( (dent = readdir (d)) )
 {
	/* avoid . and .. */
	if (! strcmp (dent->d_name, ".") ||
	 ! strcmp (dent->d_name, ".."))
	 continue;
	addstrtab (tab, dent->d_name);
 }
}
