Controls the issuing of warnings when the results of functions are ignored.

This pragma is compatible with the following platform targets:

68K

PowerPC

NEC V800

Intel x86

MIPS

Embedded 68K

When this pragma is on, the compiler will issue a warning when it encounters a statement that calls a function without using its result. To prevent this warning, cast the statement with (void).

To check whether this option is on, use __option (warn_resultnotused), described in "Checking Options." For more information about this warning see "Finding Ignored Function Results."
