Whats the correct C# datatype (or marshalling function or something) to use
when you're importing a function that has a signature similar to
char* FuncA(char c)
?
Assuming you know that both the parameter for the function and the return
value are c-style strings?

I'm trying to make a sort of conditional compilation in my C# code because
my app is intended to run on both a Pocket PC and on a normal desktop PC. My
code uses a call to an API function that on the PPC is located in
coredll.dll and on the desktop in kernel32.dll. I could make two versions of
the DllImported funktions but then I would have to...

Now I've made a dll out of this code and use it with DllImport in a C#
console application.
Basically I just access main() and pass my parameters.
w00t! RAM used by the C# app is now 228...

Good Afternoon,
I recently noticed that some very simple methods of a template declared and
used in a DLL library get inlined when used by the DLL itself, but not by
other DLLs and EXEs. After some investigating, I narrowed this down to a
very odd behavior (bug?) of the VC++.NET 2003 compiler: If a class that is
declared as...

I'm sure I'm missing something basic.
I have an class library that uses an unmanaged dll.
Let's say the class library is called "CL1.dll" and is located at:

Hello, dear all,
I often see these two import usage in the code. Both are the interface
to use the Dll library. I think they are the same.
Normally P/Invoke means using the to import the
dll. But I have some confusion about them.
1. Is the "_declspec(dllimport)" also one of the forms of P/Invoke?
2. From performance aspect, which way...
