### Function

# GLibutf8_to_utf16

#### Declaration [src]

    gunichar2*
    g_utf8_to_utf16 (
      const gchar* str,
      glong len,
      glong* items_read,
      glong* items_written,
      GError** error
    )

#### Description [src]

Convert a string from UTF-8 to UTF-16.

A nul character (U+0000) will be added to the result after the converted text.

#### Parameters

`str`

  Type: `const gchar*`

  A UTF-8 encoded string.

  The data is owned by the caller of the function.
  The value is a NUL terminated UTF-8 string.

`len`

  Type: `glong`

  The maximum length (number of bytes) of `str` to use. If `len` is negative, then the string is nul-terminated.

`items_read`

  Type: `glong*`

  Location to store number of bytes read, or `NULL` to ignore. If `NULL`, then `G_CONVERT_ERROR_PARTIAL_INPUT` will be returned in case `str` contains a trailing partial character. If an error occurs then the index of the invalid input is stored here. The value stored here will never be negative.

  The argument will be set by the function.
  The argument can be `NULL`.

`items_written`

  Type: `glong*`

  Location to store number of `gunichar2` written, or `NULL` to ignore. The value stored here does not include the trailing nul, and will never be negative.

  The argument will be set by the function.
  The argument can be `NULL`.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the function if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: `gunichar2*`

A pointer to a newly allocated UTF-16 string. This value must be freed with `g_free()`.

The caller of the function takes ownership of the data, and is responsible for freeing it.
