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)

wValue
for hub.req's
SET_FEATURE
is 0x0008
