In microsoft rpc Rpc_Binding_vector  is a data structure, defined in header  rpcdce.h. It contains two elements, 1. count  showing number of binding handles in binding handle array 2. array of binding handles
In include file rpcdce.h the array size has been given as 1.
My doubt is it any way possible for a binding vector to have more than one binding handle ? if yes how?

Let's take the following structure as an example:

    struct X
    {
        long count;
        int elements[1];
    };

The thing to remember is that the difference between "real macho" languages like C and wimpy Wirth languages is that in C it is legal, moral and accepted to lie to the compiler.
C allows accessing out-of-bounds array elements.  The following code is legal:

    struct X x;
    x.elements[0] = x.elements[42] = x.elements[-1000];

The compiler will happily generate code to access the n'th element, whatever n is.
So, the tricky part is allocating enough elements.  Static and automatic allocations will not work (obviously) but then, there's malloc().

Let's write a function that will return a pointer to a dynamically allocated structure with n elements (modulo typing errors):

    struct X * AllocateStruct(int n)
    {
        struct X *p = (struct X *) malloc(sizeof(long) + n * sizeof(int));
        p->count = n;
        return p;
    }

And use it thus:

    struct X *px;
    px = AllocateStruct(100);
    /* Do some stuff involving px */
    free(px);

OK?
