Description

Callback invoked whenever an inclusion directive of any kind (\c \#include \c \#import etc.) has been processed, regardless of whether the inclusion will actually result in an inclusion.

Declared at: clang/include/clang/Lex/PPCallbacks.h:458

Parameters

clang::SourceLocation HashLoc
The location of the '#' that starts the inclusion directive.
const clang::Token& IncludeTok
The token that indicates the kind of inclusion directive, e.g., 'include' or 'import'.
