FormatValue

Use FormatValue to specify the output formatting of numeric values. A string

can be included in the decoding definition, too. This entry can also be used to

specify default behaviors. Formatting is controlled using standard C language

printf format conversion characters. The structure of FormatValue is

FormatValue=<string>

The conversion specification is contained within the string. The following example

is taken from the wIndex definition for SET_FEATURE in the hub.req file:

0x23={

FormatValue=Port # %I

}

Here is an example of possible output:

By changing the FormatValue definition as follows,

FormatValue=Cheese (0x%03x)

for hub.req's SET_FEATURE is 0x0008
