CATC Version 1.0

2.4.9 ITrace::GetPacket

Retrieves raw packet representation.

Syntax

HRESULT GetPacket (

[in] long packet_number,

[in, out] VARIANT* packet,

[out, retval] long* number_of_bits );

Parameters

• packet_number – number of packet to retrieve

• packet – raw packet representation

• number_of_bits – number of bits in raw packet representation

Return values

• ANALYZERCOMERROR_INVALIDPACKETNUMBER – specified packet number is

invalid

Remarks

packet parameter has VT_ARRAY | VT_VARIANT

actual automation type. Each ele-

ment of this array has

VT_UI1 automation type. Since the last element of the array may

contain extra data, you need to use

number_of_bits parameter to determine actual

packet data.

Example

VBScript:

<OBJECT

ID = Analyzer

CLASSID = "clsid:0B179BC1-DC61-11D4-9B71-000102566088" >

</OBJECT>

<!--

Function DecToBin(Param, NeedLen)

While Param > 0

Param = Param/2

If Param - Int(Param) > 0 Then

Res = CStr(1) + Res

Else

Res = CStr(0) + Res

End If

Param = Int(Param)

Wend

DecToBin = Replace( Space(NeedLen - Len(Res)), " ", "0")

& Res

End Function
