Imports

cpp	Provides classes and predicates for working with C/C++ code.

Predicates

affectedByMacro	Holds if `element` is affected by a macro.
inMacroExpansion	Holds if `element` is in the expansion of a macro.
inSystemMacroExpansion	Holds if `element` is in the expansion of a macro from a system header.
macroLine	Holds if there is a macro invocation on line `line` of file `f`.
macroLocation	Holds if `l` is the location of a macro.
possibleMacroLocation	Holds if there might be a macro invocation at location `l`.

Classes

Macro	A macro. For example, the macro `MYMACRO` in the following code: `#define MYMACRO 1`
MacroAccess	A macro access. For example: `#ifdef MACRO1 // this line contains a MacroAccess int x = MACRO2; // this line contains a MacroAccess #endif`
MacroInvocation	A macro invocation (macro access that is expanded). For example: `#ifdef MACRO1 int x = MACRO2; // this line contains a MacroInvocation #endif`
