MCS_getControlValues

Returns the current value for a list of MCCS controls

Declaration

ibool NAPI MCS_getControlValues(
N_int32 numControls,
uchar *controlCodes,
ushort *values)

Prototype In

snap/ddc.h

Parameters

numControls | Number of control values to read (40 max)
controlCodes | Array of MCCS control codes (MCS_controlsType)
values | Array to store the current value for each control

Return Value

True if the function succeeded, false if it failed.

Description

This function gets the current value for multiple MCCS controls at a time. This function is similar to MCS_getControlValue, but is much faster for reading the value of multiple controls due to the reduced traffic over the I2C bus.

Note: This function can only read up to 40 controls at a time. If you need to read more than 40 controls, you will need to call this function mutiple times.
