Controls the availability of runtime type information.

This pragma is compatible with the following platform targets:

68K

PowerPC

NEC V800

Intel x86

MIPS

Embedded 68K

When this pragma is on, you can use runtime type information (or RTTI) features, such as dyanamic_cast and typeid. The other RTTI expressions are available even if the Enable RTTI option is off. Note that *type_info::before(const type_info&) is not yet implemented.

This pragma corresponds to the Enable RTTI option in the C/C++ Language Panel. To check whether this option is on, use __option (RTTI), described in "Checking Options."
