How to extract a string from a buffer ?

Hiya,

I need to extract a string (ascii) from a buffer, my buffer is

dim buf(1023) as byte

This buffer containg an "array" of type xxx

type xxx is defined in C as follows

typedef struct{
long x1
long x2
char text[0]
} xxx ;

The text field conaint a C style string zero (ascii), so although
I know the string begins at buf(8), i need to scan until I find
the zero to get the length. Then, there is a 32 bit alignment and
another xxx item, etc.

One idea which I thought about was while I am looking for the
zero, to build the string as follows:

s=s+chr(buf(i))

but this is going to be slow, is there some sort of other way,
something elegant and vb-atomic (i.e. without a for loop) ?

Call the GetString method on the appropriate System.Text.Enc oding
subclass.
