Marshal a dummy Haskell string into a NUL terminated C wide string using temporary storage.
- the Haskell string is created by length parameter. And the Haskell string contains only NUL characters.
- the memory is freed when the subcomputation terminates (either normally or via an exception), so the pointer to the temporary storage must not be used after this.
withTStringBufferLen :: Int -> ((LPTSTR, Int) -> IO a) -> IO a Source #
Marshal a dummy Haskell string into a C wide string (i.e. wide character array) in temporary storage, with explicit length information.
- the Haskell string is created by length parameter. And the Haskell string contains only NUL characters.
- the memory is freed when the subcomputation terminates (either normally or via an exception), so the pointer to the temporary storage must not be used after this.
