#define kTestState | ( |  | EXPRESSION | ) | kTestState_(EXPRESSION)

If the EXPRESSION argument does not evaluate to kTRUE, kERROR_STATE is passed to an error-handling block. Otherwise, execution continues at the next statement.

This macro is guaranteed to evaluate its arguments only once.

Parameters

  EXPRESSION | Expression that evaluates to a kBool value.
