Syntax

Linux:

-check-pointers=keyword

OS X:

None

Windows:

/Qcheck-pointers:keyword

Arguments

keyword

Specifies what type of bounds checking occurs. Possible values are:

none	Disables bounds checking. This is the default.
rw	Checks bounds for reads and writes through pointers.
write	Checks bounds for only writes through pointers.

Default

-check-pointers=none or /Qcheck-pointers:none

No bounds checking occurs for memory access through pointers.

Description

This option determines whether the compiler checks bounds for memory access through pointers. It enables checking of all indirect accesses through pointers, and all array accesses.

The compiler may optimize these checks away when it can determine that an access is safe.

When rw or write is specified, the [Q]check-pointers-undimensioned option is set and dimensioned and undimensioned arrays are checked.

If you do not want undimensioned arrays checked, you must specify option the negative form of the option (see Syntax above).

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