#include <eckit/types/FixedString.h>
template<int SIZE>
eckit::FixedString class

FixedString<SIZE> manages a SIZE-byte char array as a relatively thin utility wrapper.

  • Strings <= the given SIZE may be stored
  • Strings shorter than the given SIZE are null-character terminated
  • All relevant overflow and termination safety is handled internally inside the class when interacting with C library functions.
