IDL 4.2 · §7.4.1.4.4.4

String & wstring

string and wstring are variable-length character sequences, optionally bounded. A bound becomes a validation limit and informs buffer sizing; unbounded strings are length-prefixed on the wire.

Example

struct Label {
  string<64> name;   // bounded
  string     note;   // unbounded
};
