unsigned char * problem

[sansknowledge]

hello all
i am new to this forum, i have some knowledge in c++. I am developing a win32 dll using vc++ 6.0 in winxp sp2 using a third party SDK my problem is
the sdk is having a few structures
1)

typedef struct SKYETEK_ID 
{
    unsigned char   *id;
    unsigned int    length;
} SKYETEK_ID, *LPSKYETEK_ID;

2)

typedef struct SKYETEK_TAG 
{
  SKYETEK_TAGTYPE     type;
  LPSKYETEK_ID        id;
  unsigned short      afi;
  unsigned short      session;
  unsigned char       rf;
  TCHAR                friendly[128];
  void                *user;
  void                *internal;
} SKYETEK_TAG, *LPSKYETEK_TAG;

3)

unsigned char SelectLoopCallBack(LPSKYETEK_TAG lpTag, void *user)
{
    char* tid;
    unsigned char *ttype;
    if( !isStop )
    {
        if (lpTag!=NULL)
            {
 
            tid=(SkyeTek_GetTagTypeNameFromType(lpTag->type));
            ttype=lpTag->id; 
            MessageBox(0,ttype,"test",0);
 
            USES_CONVERSION;
            MyTagid =A2BSTR(tid);
            MyTagType=A2BSTR(ttype); 
            SkyeTek_FreeTag(lpTag);
 
            }
    }
 
return isStop;
}

in the third function i am calling the second structure as lpTag.
i want the tag id which is pointing to another structure with unsigned char* as data type.
so i created a local unsigned char* variable and try to store the lptag->id value into it. what returns is some thing gibberish.how get the correct value from the structure and store it in a char * any help will be greatly appreciated.tha nks and regards

I guess you didnt allocate memory for your "unsingned char * id"

how to do that ? (a bit naive)
