Utilities
escapeChar :: Char -> String #
unescapeChar :: String -> (Char, String) #
unescapeString :: String -> String #
C char constants (and multi-character character constants)
construct a character constant from a haskell Char
Use cchar_w if you want a wide character constant.
C char constants (abstract)
getCCharAsInt :: CChar -> Integer #
get integer value of a C char constant undefined result for multi-char char constants
isWideChar :: CChar -> Bool #
return true if the character constant is wide.
showCharConst :: Char -> ShowS #
showCharConst c prepends _a_ String representing the C char constant corresponding to c.
If necessary uses octal or hexadecimal escape sequences.
C integral constants
datatype representing type flags for integers
Constructors
| FlagUnsigned | |
| FlagLong | |
| FlagLongLong | |
| FlagImag |
datatype for memorizing the representation of an integer
cInteger :: Integer -> CInteger #
construct a integer constant (without type flags) from a haskell integer
getCInteger :: CInteger -> Integer #
C floating point constants
Floats (represented as strings)
readCFloat :: String -> CFloat #
C string literals
C String literals
getCString :: CString -> String #
showStringLit :: String -> ShowS #
showStringLiteral s prepends a String representing the C string literal corresponding to s.
If necessary it uses octal or hexadecimal escape sequences.
concatCStrings :: [CString] -> CString #
concatenate a list of C string literals
Clang C version literals
data ClangCVersion #
Clang dotted version literal https://clang.llvm.org/docs/AttributeReference.html#availability
