| Name | Description |
|---|---|
| dstVector | destination for the null-terminated UTF-8 result |
| srcString | UTF-32 source buffer to convert |
| srcStringLength | number of UTF-32 values to convert |
| numCodePointsWritten | if non-null, receives the number of UTF-8 code points written |
| errorByte | optional substitute for invalid UTF-32 values; 0 writes nothing |
| byteOrder | byte order of the UTF-32 input (host by default) |
