# Simple API

parseC :: InputStream -> Position -> Either ParseError CTranslUnit

`parseC input initialPos` parses the given preprocessed C-source input and returns the AST or a list of parse errors.

# Parser Monad

data P a

Monad P |

execParser :: P a -> InputStream -> Position -> [Ident] -> [Name] -> Either ParseError (a, [Name])

execute the given parser on the supplied input stream. returns `ParseError` if the parser failed, and a pair of result and remaining name supply otherwise

Synopsis: `execParser parser inputStream initialPos predefinedTypedefs uniqNameSupply`

execParser_ :: P a -> InputStream -> Position -> Either ParseError a

run the given parser using a new name supply and builtin typedefs see `execParser`

Synopsis: `runParser parser inputStream initialPos`

builtinTypeNames :: [Ident]

# Exposed Parsers

translUnitP :: P CTranslUnit

`translUnitP` provides a parser for a complete C translation unit, i.e. a list of external declarations.

extDeclP :: P CExtDecl

`extDeclP` provides a parser for an external (file-scope) declaration

statementP :: P CStat

`statementP` provides a parser for C statements

expressionP :: P CExpr

`expressionP` provides a parser for C expressions

# Parser Monad
