direntry - read directory entries

#include <direntry.h>

DIR *opendir(fn);

struct direntry *readdir(dir);

void closedir(dir);

DIR *dir;
char *fn;

The point of direntry.h is to provide a uniform interface to BSD's sys/dir.h and POSIX's dirent.h.

The readdir interface is highly unsatisfactory. It does not distinguish between I/O errors and end-of-directory. It uses malloc. The return type for closedir varies: some implementations return the close return value.
