[MAYA API] How to get a array optionVar in C++

[Sun Dawei]

Hello,

Merry Christmas and Happy New Year!

I have a question about optionVars in maya, I could not find any api that can query and set array optionVars, there are only MGlobal::optionVarIntValue, MGlobal::optionVardoubleValue, MGlobal::optionVarStringValue in maya api. is there a way to get and set(append) to a int (or double) array?

thanks
