Description

Scan the input for the preprocessor directives that might have an effect on the dependencies for a compilation unit. This function ignores all non-preprocessor code and anything that can't affect what gets included.

Declared at: clang/include/clang/Lex/DependencyDirectivesScanner.h:113

Parameters

llvm::StringRef Input

SmallVectorImpl< dependency_directives_scan::Token>& Tokens

SmallVectorImpl< dependency_directives_scan::Directive>& Directives

clang::DiagnosticsEngine* Diags = nullptr

clang::SourceLocation InputSourceLoc = clang::SourceLocation()

Returns

false on success, true on error. If the diagnostic engine is not null, an appropriate error is reported using the given input location with the offset that corresponds to the \p Input buffer offset.
