org.graalvm.nativeimage.c.struct.SizeOf
public final class SizeOf extends Object
Contains static methods that provide access to the size of dereferenced SystemJava pointer types (i.e. the size of the data structure pointed-to by SystemJava pointer). Note that this semantic differs from the sizeof-operator defined by the C programming language.
