Conditional Compilation

Conditional Compilation

Conditional compilation works similar to the C preprocessor's conditional compilation. The following preprocessor directives may be used:

Directive	Meaning
#ifdef symbol	If symbol is defined then compile the following code
#ifndef symbol	If symbol is not defined then compile the following code
#else	Switch from compiling to not compiling and vice versa
#endif	Return to previous compiling state
#if condition	If the condition evaluates to true then compile the following code
#elif	Same as #else but used with #if

See the NXTDefs.h header files for many examples of how to use conditional compilation.
