Not so -- it thinks you're declaring a function named CreateNamedPipe.

Again, not really -- this is attempting to declare a function named
CreateNamedPipe that takes no parameters and returns a HANDLE. Assuming
you've included windows.h (which declares CreateNamedPipe to take 8
parameters) you'll get an error from the compiler saying the
declarations conflict with each other.

Fortunately, the cure you've given is correct anyway -- use something
like:

Handle pipeHandle = CreateNamedPipe(...);

and all is well.

Given that the "declaration" passes numbers and a string instead of type
names, I'm right. See below.

To declare it as taking no parameters, I would have had to say:

HANDLE CreateNamedPipe( void );
^^^^ note void not NULL
or:
HANDLE CreateNamedPipe();

To declare a function, the tokens between the () must be named or
unnamed parameter specifications, as in the following:

HANDLE CreateNamedPipe( int );
HANDLE CreateNamedPipe( int pipenum );
HANDLE CreateNamedPipe( int (*)() (*func)(int i, char c, float) );
(last is "pointer to function taking int, char, float and returning
pointer to function taking no parameters and returning int.")

Since NULL is a constant typically #defined as ((void *)0), it can't be
a parameter specification.

In that case, we fall back to a constructor-syntax initialiser, which
works just fine with C++ primitive data types (integers, floating point,
pointers). These are equivalent:

HANDLE h(NULL);
HANDLE h = NULL;

In plain C, the first would be an error, but as this is in a class, I
feel safe in allowing C++ syntax.

Absolutely true -- clearly I should have been in bed instead of posting
