This function uses the parameters supplied and generates a binding

It is assumed that binding over named pipe uses static end point

|
with the interface name and options as provided.

Arguments:
|
|
pBindingHandle pointer to location which will contain binding handle
|

on successful return
|
|
pwszServerName pointer to string containing the name of the server
|
|
to which, this function will obtain a binding.
|
|
pwszInterfaceName pointer to string containing the interface name
|
|
pwszOptions pointer to string containing any additional options for

binding.

Returns:

Also on success, the binding handle is stored in pBindingHandle.

It should freed after usage, using the RpcBindingFree() function.
