MCS_getControlValue

Returns the current value for an MCCS control

Declaration

ibool NAPI MCS_getControlValue(
uchar controlCode,
ushort *value)

Prototype In

snap/ddc.h

Parameters

controlCode | MCCS control code (MCS_controlsType)
value | Place to store the current value for the control

Return Value

True if the function succeeded, false if it failed.

Description

This function obtains the current value for a specified MCCS control for the attached monitor. Continuous controls may accept any value between zero and the maximum value, specific to each control. Non-continuous controls can only accept specific values. A value of 0 for non-continous controls represents that no value has been selected.

Note: If you need to retrieve the values of multiple controls at a time, you should use the more efficient MCS_getControlValues function which can read multiple control values directly from the monitor in a single packet.
