MCS_getControlMax
Returns the maximum value for an MCCS control
Declaration
ibool NAPI MCS_getControlMax(
uchar controlCode,
ushort *max)
Prototype In
snap/ddc.h
Parameters
controlCode |
MCCS control code (MCS_controlsType) |
max |
Place to store the maximum value for the control |
Return Value
True if the function succeeded, false if it failed.
Description
This function obtains the maximum 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. The maximum value returned for non-continuous controls represents the maximum index for the acceptable values for the control. A value of 0 for non-continous controls represents that no value has been selected.
Note: This function internally reads the maximum value from the attached monitor only once for each control between an MCS_begin and MCS_end block. If you call it again after the maximum value for a control has been read, it simply returns an internal cached value for maximum performance.
