Enumerations
enum	clang::ento::errno_modeling::ErrnoCheckState : unsigned { clang::ento::errno_modeling::Irrelevant = 0, clang::ento::errno_modeling::MustBeChecked = 1, clang::ento::errno_modeling::MustNotBeChecked = 2 }
	Describe how reads and writes of errno are handled by the checker. More...

Functions
Optional< SVal >	clang::ento::errno_modeling::getErrnoValue (ProgramStateRef State)
	Returns the value of 'errno', if 'errno' was found in the AST. More...
ErrnoCheckState	clang::ento::errno_modeling::getErrnoState (ProgramStateRef State)
	Returns the errno check state, Errno_Irrelevant if 'errno' was not found (this is not the only case for that value). More...
Optional< Loc >	clang::ento::errno_modeling::getErrnoLoc (ProgramStateRef State)
	Returns the location that points to the MemoryRegion where the 'errno' value is stored. More...
ProgramStateRef	clang::ento::errno_modeling::setErrnoValue (ProgramStateRef State, const LocationContext *LCtx, SVal Value, ErrnoCheckState EState)
	Set value of 'errno' to any SVal, if possible. More...
ProgramStateRef	clang::ento::errno_modeling::setErrnoValue (ProgramStateRef State, CheckerContext &C, uint64_t Value, ErrnoCheckState EState)
	Set value of 'errno' to a concrete (signed) integer, if possible. More...
ProgramStateRef	clang::ento::errno_modeling::setErrnoState (ProgramStateRef State, ErrnoCheckState EState)
	Set the errno check state, do not modify the errno value. More...
bool	clang::ento::errno_modeling::isErrno (const Decl *D)
	Determine if a Decl node related to 'errno'. More...
const char *	clang::ento::errno_modeling::describeErrnoCheckState (ErrnoCheckState CS)
	Produce a textual description about how errno is allowed to be used (in a ErrnoCheckState). More...
const NoteTag *	clang::ento::errno_modeling::getErrnoNoteTag (CheckerContext &C, const std::string &Message)
	Create a NoteTag that displays the message if the 'errno' memory region is marked as interesting, and resets the interestingness. More...
ProgramStateRef	clang::ento::errno_modeling::setErrnoForStdSuccess (ProgramStateRef State, CheckerContext &C)
	Set errno state for the common case when a standard function is successful. More...
ProgramStateRef	clang::ento::errno_modeling::setErrnoForStdFailure (ProgramStateRef State, CheckerContext &C, NonLoc ErrnoSym)
	Set errno state for the common case when a standard function fails. More...
const NoteTag *	clang::ento::errno_modeling::getNoteTagForStdSuccess (CheckerContext &C, llvm::StringRef Fn)
	Generate the note tag that can be applied at the state generated by setErrnoForStdSuccess . More...
