packCString :: CString -> IO ShortByteString

O(n). Construct a new ShortByteString from a CString. The resulting ShortByteString is an immutable copy of the original CString, and is managed on the Haskell heap. The original CString must be null terminated.

Since: bytestring-0.10.10.0

packCStringLen :: CStringLen -> IO ShortByteString

O(n). Construct a new ShortByteString from a CStringLen. The resulting ShortByteString is an immutable copy of the original CStringLen. The ShortByteString is a normal Haskell value and will be managed on the Haskell heap.

Since: bytestring-0.10.10.0

useAsCString :: ShortByteString -> (CString -> IO a) -> IO a

O(n) construction. Use a ShortByteString with a function requiring a null-terminated CString. The CString is a copy and will be freed automatically; it must not be stored or used after the subcomputation finishes.

Since: bytestring-0.10.10.0

useAsCStringLen :: ShortByteString -> (CStringLen -> IO a) -> IO a

O(n) construction. Use a ShortByteString with a function requiring a CStringLen. As for useAsCString this function makes a copy of the original ShortByteString. It must not be stored or used after the subcomputation finishes.
