hello guys this is my code for the C# wrapper.
================================using System;
using System.Runtime.InteropServices;
using System.IO;
namespace Speex
{
///<summary>
///the following class is the win32 SPEEX API that retrieve
///methods and structures from the libspeex file

public unsafe class Speex_win32
{
#region Speex Constants
//global speex file that contains the api(s)
public const string libpath = "libspeex.dll";
public const int Frame_Size = 160;
public const int Max_Frame_Size = 2000;
public const int Speex_Get_Frame_Size = 3;
public const int Speex_Set_Quality = 4;
public const int Speex_nb_Mode = 3;
//create the structure that will hold the speexbits
public struct SpeexBits
{
public char *chars; /* "raw" data */
public int nbBits; /* Total number of bits stored in thestream*/
public int charPtr; /* Position of the byte "cursor" */
public int bitPtr; /* Position of the bit "cursor" within thecurrent
char */
public int owner; /* Does the struct "own" the "raw"
buffer(member "chars") */
public int overflow; /* Set to one if we try to read past thevalid data */
public int buf_size; /* Allocated size for buffer */
public int reserved1; /* Reserved for future use */
public void *reserved2; /* Reserved for future use */
}

public struct SpeexMode

}
}
when i call the speex_lib_get_mode(int modein);
in my managed code i have an exception with the message "unable to find an
entrypoint for the speex_lib_get_mode in the libspeex.dll file"
please help is there anything something wrong in my wrapper please help or
correct my file please.
