PS_MODIFIERRANGE

code: 168

# set
<module-index>/<port-index> PS_MODIFIERRANGE [<stream_index>, <modifier_index>] <min_val> <step> <max_val>

# get
<module-index>/<port-index> PS_MODIFIERRANGE [<stream_index>, <modifier_index>] ?

Description

Range specification for a packet modifier for a stream header, specifying which values the modifier should take on. This applies only to incrementing and decrementing modifiers; random modifiers always produce every possible bit pattern. The range is specified as three values: mix, step, and max, where max must be equal to min plus a multiple of step. Note that when “decrement” is specified in PS_MODIFIER as the action, the value sequence will begin with the max value instead of the min value and decrement from there: {max, max-1, max-2, …, min, max, max-1…}.

Actions

set, get

Parameters

min_val: integer, the minimum modifier value, from 0 to 65535.
step: integer, the increment between modifier values, from 1 to 15.
max_val: integer, the maximum modifier value, from 0 to 65535.
