9.3 GetDecodedScriptField()

Extracts information about the script decoded field and determines how it is shown in the USB Protocol Suite

trace view or the "View … Fields" dialog.

Format : GetDecodedScriptField ( fld_name )

Parameters:

fld_name Name of the field supposedly existing in the current Transfer

Return Values:

If the field name is in the current Transfer, the return value is the text value of the decoded field and how to

display it in the trace. Otherwise, the return value is the empty string.

Example:

# Extract the decoded value of wValue field

# for a Control transfer that uses a certain Class

# or Vendor specific decoding.

str = GetDecodedScriptField ("wValue");

# If the bulk transfer payload decoded by the script decoder

# has a field named 'Code' (i.e., PTP transfers):

str = FormatEx( " Code(str) = '%s' ", GetDecodedScriptField ( "Code" ) );

Remarks:

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

This function can be used only at the Transfer level.
