OptionalFileEntryRef DirectoryLookup::LookupFile	(	StringRef &	Filename,
		HeaderSearch &	HS,
		SourceLocation	IncludeLoc,

		bool	OpenFile = `true`
	)		const

LookupFile - Lookup the specified file in this search path, returning it if it exists or returning null if not.

Parameters

	Filename	The file to look up relative to the search paths.
	HS	The header search instance to search with.
	IncludeLoc	the source location of the #include or #import directive.
	SearchPath	If not NULL, will be set to the search path relative to which the file was found.
	RelativePath	If not NULL, will be set to the path relative to SearchPath at which the file was found. This only differs from the Filename for framework includes.
	RequestingModule	The module in which the lookup was performed.
	SuggestedModule	If non-null, and the file found is semantically part of a known module, this will be set to the module that should be imported instead of preprocessing/parsing the file found.
[out]	InUserSpecifiedSystemFramework	If the file is found, set to true if the file is located in a framework that has been user-specified to be treated as a system framework.
[out]	IsFrameworkFound	For a framework directory set to true if specified '.framework' directory is found.
[out]	MappedName	if this is a headermap which maps the filename to a framework include ("Foo.h" -> "Foo/Foo.h"), set the new name to this vector and point Filename to it.

◆ setSearchedAllModuleMaps()

void clang::DirectoryLookup::setSearchedAllModuleMaps ( bool SAMM )

inline

Specify whether we have already searched all of the subdirectories for module maps.
