8.3.2 @encode

GNU Objective-C supports the @encode syntax that allows you to create a type encoding from a C/Objective-C type. For example, @encode(int) is compiled by the compiler into "i".

@encode does not support type qualifiers other than const. For example, @encode(const char*) is valid and is compiled into "r*", while @encode(bycopy char *) is invalid and will cause a compilation error.
