9.2 GetHexPktField()

Extracts the raw hexadecimal value of the USB3 packet field.

Format : GetHexPktField ( fld_name )

Parameters

fld_name Name of the field supposedly existing in the current packet

Return Values

If the field name is in the current packet, the function returns the hex value of the decoded field:

o integer value if field length is less than 32 bits

o raw binary value if field length is greater than 32 bits. The raw binary value gives a list of bytes.

See the CSL Manual for further details about raw binary values.

o null value if the field was not found.

Example

# Link Control Word

if( ( in.TraceEvent == _USB3_TP_PKT ) ||

( in.TraceEvent == _USB3_DP_PKT ) )

{

ReportText( "LCW:" );

val = GetHexPktField ( "Hseq" );

str = FormatEx( "\tHseq = %d", val );

ReportText( str );

val = GetHexPktField ( "Hdepth" );

str = FormatEx( "\tHDepth = %d", val );

ReportText( str );

val = GetHexPktField ( "D1" );

str = FormatEx( "\tDelayed (D1) = %d", val );

ReportText( str );

val = GetHexPktField ( "D2" );

str = FormatEx( "\tDeferred (D2) = %d\n", val );

ReportText( str );

}

Remark

The field name should be exactly the same as it is in the trace. The field name is case sensitive.
