perror() is your friend.

    if (retcode) perror("unlink");

    if (retcode) perror("chmod");
C>  fd = open ("aPipe", O_RDONLY);
    if (fd < 0) perror("open");

C> return code for all functions is -1.

prints:

unlink: No such file or directory
mknod: Function not implemented
chmod: No such file or directory
open: No such file or directory

which should be sufficient to answer your question.
