NAME

set_led_rgb - Set the specific R,G,B values for an individual LED on a specific controller.

SYNOPSIS

bool
set_led_rgb( controlid, ledid, r, g, b, buffer )

DESCRIPTION

Set the color value of an individual LED on a known LED controller and returns -1 if the controlid does not exist, if ledid is not a valid index, if the controlid backed device lacks the r,g,b capability. A negative ledid will result in the value being set for all LED s associated with the device. A return of 0 means that the update failed as it would block the device. This can happen if many LED update queries are being pushed to a slow device. If the optional boolean buffer is set, the request may be queued and the queue will not dispatch until a non-buffered update is called.
