MEMCU24 converts the data in a source buffer from UTF-16 to UTF-32, stores the result in a target buffer, and returns an unscaled REAL FIXED BINARY value specifying the number of bytes written to the target buffer.
|
The buffer lengths must have computational type and will be converted to FIXED BINARY(31,0).
The buffer lengths must be nonnegative.
If the target buffer is too small or if the source UTF-16 is invalid, a value of -1 is returned.
On z/OS, this built-in function requires an ARCH level of 7 or higher.
