restrict, Qrestrict

Determines whether pointer disambiguation is enabled with the restrict qualifier.

Syntax

Linux and OS X:

-restrict

-no-restrict

Windows:

/Qrestrict

/Qrestrict-

Arguments

None

Default

-no-restrict or /Qrestrict-

Pointers are not qualified with the restrict keyword.

Description

This option determines whether pointer disambiguation is enabled with the restrict qualifier. Option -restrict and /Qrestrict enable the recognition of the restrict keyword as defined by the ANSI standard.

By qualifying a pointer with the restrict keyword, you assert that an object accessed by the pointer is only accessed by that pointer in the given scope. You should use the restrict keyword only when this is true. When the assertion is true, the restrict option will have no effect on program correctness, but may allow better optimization.

IDE Equivalent

Xcode: None
