Class BufferChecks

java.lang.Object
org.lwjgl.BufferChecks
public class BufferChecks extends Object

A class to check buffer boundaries in general. If there is unsufficient space in the buffer when the call is made then a buffer overflow would otherwise occur and cause unexpected behaviour, a crash, or worse, a security risk. Internal class, don't use.

      public static void checkBufferSize(Buffer buf, int size)
      Helper method to ensure a buffer is big enough to receive data from a glGet* operation.
      Parameters:
