man getdents:

int getdents(unsigned int fd, struct dirent *dirp, unsigned int count);

       The  system  call  getdents  reads  several  dirent structures from the
       directory pointed at by fd into the memory area  pointed  to  by  dirp.
       The parameter count is the size of the memory area.
