InterlockedMax() 공개 정적인 메소드

Performs a guaranteed atomic max.
This method is an intrinsic and can only be used within a shader on the GPU. Using it on the CPU is undefined behavior.
public static InterlockedMax ( int destination, int value ) : void
destination int The destination value.
value int The input value.
