terminated :: ManagedCString -> Bytes Source #
unterminated :: ManagedCString -> Bytes Source #
fromBytes :: Bytes -> ManagedCString Source #
Copies the slice, appending a NUL byte to the end.
fromLatinString :: String -> ManagedCString Source #
Convert a String consisting of only characters representable
by ISO-8859-1. These are encoded with ISO-8859-1. Any character
with a codepoint above U+00FF is replaced by an unspecified byte.
pinnedFromBytes :: Bytes -> ManagedCString Source #
Copies the slice into pinned memory, appending a NUL byte to the end.
pin :: ManagedCString -> ManagedCString Source #
touch :: ManagedCString -> IO () Source #
contents :: ManagedCString -> CString Source #
Get a pointer to the payload of the managed C string. The behavior is undefined if the argument is not pinned.
