void (*vector[])( )
can be simplied (in terms of readability) as
typedef void (*PF) ();
PF vector[];

If you also mention cdecl(1), the OP might answer the next question
himself.
From the manpage:
Cdecl (and c++decl) is a program for encoding and decoding C (or
C++) type declarations.

Don't forget to put important parts of your message in the message. It
is not sufficient to hide that information in a header.
"void (*vector[])( )" declares vector as an array of pointers to
functions with an unspecified argument list and returning nothing.

This is an array of functions each with no (undefined) argument list
that return void. It can be made easier to understand ysing a typdef
for the function

That should be "array of pointers to functions", you cannot have an "array
of functions" in C.

Almost. It is an array of *pointer to* function. The parameter list
of the function is *unspecified*, which does not necessarily mean the
function takes no arguments.

Hello all,
I am using C++ to convert a certain file into an XML file. During the
conversion the program does some arithmetic operations on the
information that is then outputted in xml format. The information is
a double variable.
Usually the output is exactly what it should be, but every so often
the output is "-1.#J".

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
