Chapter 5

Pointers and Arrays

Pointers are memory addresses of data objects in the operating system kernel or in the address space of a user process. D provides the ability to create and manipulate pointers and store them in variables and associative arrays. This chapter describes the D syntax for pointers, operators that can be applied to create or access pointers, and the relationship between pointers and fixed-size scalar arrays. Also discussed are issues relating to the use of pointers in different address spaces.

Note - If you are an experienced C or C++ programmer, you can skim most of this chapter as the D pointer syntax is the same as the corresponding ANSI-C syntax. You should read Pointers to DTrace Objects and Pointers and Address Spaces as they describe features and issues specific to DTrace.
