Hi

The declaration exists:
Code:
MPFUN int MPAPI GetSignatureCertInBuffer(void *CTX, int Index, char **Buf, int *Len);


The parameter Buf may be NULL

Please, help. I don't know how translate it to C#

It's correct?
Code:
[DLLImport("..." ... )]
public static extern int GetSignatureCertInBuffer(IntPtr CTX, int Index, [in, out] string[] Buf, IntPtr Len)


Thanks

I would try 'IntPtr' or 'StringBuilder' for 'char** Buf'.
