class GNUNullExpr
Declaration
class GNUNullExpr : public Expr { /* full declaration omitted */ };Description
GNUNullExpr - Implements the GNU __null extension, which is a name for a null pointer constant that has integral type (e.g., int or long) and is the same size and alignment as a pointer. The __null extension is typically only used by system headers, which define NULL as __null in C++ rather than using 0 (which is an integer that may not match the size of a pointer).
