char * stringprep_ucs4_to_utf8(const uint32_t * str, ssize_t len, size_t * items_read, size_t * items_written);
- const uint32_t * str
a UCS-4 encoded string
- ssize_t len
the maximum length of str to use. If len < 0, then the string is terminated with a 0 character.
- size_t * items_read
location to store number of characters read read, or NULL.
- size_t * items_written
location to store number of bytes written or NULL. The value here stored does not include the trailing 0 byte.
Convert a string from a 32-bit fixed width representation as UCS-4. to UTF-8. The result will be terminated with a 0 byte.
Return value: a pointer to a newly allocated UTF-8 string. This value must be deallocated by the caller. If an error occurs, NULL will be returned.
