GHC.CString
GHC C strings definitions (previously in GHC.Base). Use GHC.Exts from the base package instead of importing this module directly.
Ascii variants
unpackCString# :: Addr# -> [Char] Source #
unpackFoldrCString# :: Addr# -> (Char -> a -> a) -> a -> a Source #
cstringLength# :: Addr# -> Int# Source #
Compute the length of a NUL-terminated string. This address
must refer to immutable memory. GHC includes a built-in rule for
constant folding when the argument is a statically-known literal.
That is, a core-to-core pass reduces the expression
cstringLength# "hello"# to the constant 5#.
Utf variants
unpackCStringUtf8# :: Addr# -> [Char] Source #
unpackFoldrCStringUtf8# :: Addr# -> (Char -> a -> a) -> a -> a Source #
