Description

Convert a string from UCS-4 to UTF-16. A 0 character will be added to the result after the converted text.

Parameters

str

Type: An array of gunichar

A UCS-4 encoded string.

The length of the array is specified in the len argument.
The data is owned by the caller of the function.
len

Type: glong

The maximum length (number of characters) of str to use. If len < 0, then the string is nul-terminated.

items_read

The argument can be NULL.
items_written

Type: glong*

Location to store number of #gunichar2 written, or NULL. The value stored here does not include the trailing 0.

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 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(). If an error occurs, NULL will be returned and error set.

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