# check-pointers-narrowing, Qcheck-pointers-narrowing

Determines whether the compiler enables or disables the narrowing of pointers to structure fields.

## Syntax

Linux: | -check-pointers-narrowing -no-check-pointers-narrowing

macOS: | None

Windows: | /Qcheck-pointers-narrowing /Qcheck-pointers-narrowing-

## Arguments

None

## Default

-check-pointers-narrowing or /Qcheck-pointers-narrowing | The compiler enables the narrowing of pointers to structure fields.

## Description

This option determines whether the compiler enables or disables the narrowing of pointers to structure fields. Narrowing restricts a field pointer so that it can only legally point to that field.

To use this option, you must also specify the [Q]check-pointers option.

Disabling this feature can improve Pointer Checker compatibility with non-ANSI compliant code.

To disable the narrowing of pointers to structure fields, specify the negative form of the option (see Syntax above).

This pointer checker feature requires installation of another product. For more information, see Feature Requirements.
