How to Convert TDes to unsigned char*?

[strike_noir]

Hi FN

This may be already asked in a different form. But I've looked all the post I can find about this. Still havent managed to do it.

So is anybody know how to convert an TDes to an unsigned char*?

Here is what I need to do?

void (TDes& aKey, const TInt aSize)
{
	TInt len = aKey.Length();
	unsigned char* dest = new unsigned char[len+1];
	// ??
	// copy aKey to dest ??
}

Hi,

TDes16 has method
IMPORT_C const TUint16 *PtrZ();
where TUint16 is unsigned short int.

Be mindful if you call PtrZ() as the descriptor's length must be less than its max length, also this returns a pointer to the data, not a copy of the data.

An alternative is

Mem::Copy(dest, aKey.Ptr(), aKey.Size();

and if you need to Null terminate it then:

dest[aKey.Length()] = '\0';

You might also need to convert to an 8-bit descriptor first and then use the PtrZ or copy methods described above from there. It depends what sort of data is in your descriptor. If it is basically an ASCII string then I suspect you will want to.
