C++ Data Types and Inspect

The following subsections discuss how Inspect handles and presents various C++ data

types.

Bit Fields

Inspect can access C bit fields for display or for expression evaluation. For example, in

these Inspect session the identifiers are binary objects:

Arrays

When you use an array name in an expression, Inspect interprets the array name as a

pointer value. However, when you display an unsubscripted array name, Inspect

displays a pointer value and the contents of the array. For example, assume this C

array declaration:

int z[10]

Inspect would process references to this array in these ways:



If z appears in an expression, the value of z is the address of array element z[0].



If z appears as a display item, Inspect displays the address of array element z[0]

and the contents of array z.

Structure Pointers

If you display a structure pointer but do not also select a field within the referenced

structure, Inspect displays the whole structure. To select a field within the referenced

structure, use the C++ arrow operator; for example:

-COBJ-DISPLAY this->class::field

This example shows how to display a structure and how to display the value of the

pointer to the structure:

-COBJ-DISPLAY *this COMMENT - displays the object

-COBJ-DISPLAY this COMMENT - displays the pointer value

-COBJ-DISPLAY (tstor) ;COMMENT Display value

-COBJ-DISPLAY (tstor | tstand ;COMMENT Bitwise OR

-COBJ-DISPLAY (tstand & b) ;COMMENT Bitwise AND

-COBJ-DISPLAY (tstand ^ b) ;COMMENT Bitwise XOR
