[Patrick]

Anyone have any ideas on how to Marshal this parameter in C#?

unsigned char* buf

Hi Patrick,
post it to the interop group including
the structures, signatures etc.

Patrick,

Generally speaking, that will be marshaled as a byte array, or as a
string.

However, if you are passing the buffer to be written to, and it is a
string, then you will have to pass a stringbuilder and not a string.

Hope this helps.

As a string, StringBuilder or byte[] depending on how it's used.
