MEMCU14

MEMCU14 converts the data in a source buffer from UTF-8 to UTF-32, stores the result in a target buffer, and returns a size_t ¹ value that indicates the number of bytes that are written to the target buffer.

p

Address of the target buffer.

n

Length of the target buffer.

q

Address of the source buffer.

m

Length of the source buffer.

The buffer lengths must be nonnegative and must have a computational type. The buffer lengths are converted to type size_t.

If the target buffer is too small or if the source UTF-8 is invalid, a value of -1 is returned.
