Function decoder_decode_to_utf16_without_replacement 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn decoder_decode_to_utf16_without_replacement(
    decoder: *mut Decoder,
    src: *const u8,
    src_len: *mut usize,
    dst: *mut u16,
    dst_len: *mut usize,
    last: bool,
) -> u32

Incrementally decode a byte stream into UTF-16 without replacement.

See the top-level FFI documentation for documentation for how the decoder_decode_* functions are mapped from Rust and the documentation for the Decoder struct for the semantics.

src must be non-NULL even if src_len is zero. Whensrc_len is zero, it is OK for src to be something non-dereferencable, such as 0x1. Likewise for dst when dst_len is zero. This is required due to Rust’s optimization for slices within Option.

Undefined behavior

UB ensues if any of the pointer arguments is NULL, src and src_len don’t designate a valid block of memory or dst and dst_len don’t designate a valid block of memory.
