bool
isValidCodePoint(
int* status,
char const* codePoint,
size_type numBytes);If the specified codePoint (having at least the specified numBytes) refers to a valid UTF-8 code point then return true and load the specified status with the number of bytes in the code-point; otherwise, if codePoint is not a valid code-point, return false and load status with one of the (negative) ErrorStatus constants. The behavior is undefined unless numBytes > 0.
true if codePoint is valid UTF-8, and false otherwise
| Name | Description |
|---|---|
| status | receives byte length on success, or an ErrorStatus value |
| codePoint | candidate first byte of a UTF-8 code point |
| numBytes | number of bytes available at codePoint |
