CHAPTER 6
The Ddelete() function is used to remove a subdirectory:
int status;
char ^pathname;
status = Ddelete(pathname);
where pathname points to a null-terminated ASCII string
which contains the path name of the directory to delete. If
GEMDOS is able to delete the directory, a 0 is returned in
status, otherwise, a negative GEMDOS error number is re
turned. Note that a subdirectory may only be deleted if it is
empty.
Program 6-2 below demonstrates the entire process for
obtaining a directory listing in C.
