SE_Predicate
/* * TYPEDEF: SE_Predicate * * Defines a type for a pointer to a user-defined function that can * be used in a search filter. The user-defined function must match * this signature, and returns true or false based on whether the given * test_object passes the tests the user-supplied test function. If * a link class object was encountered when retrieving the test_object, then * that link class object is also made available to the user for testing * within the test function. * * Furthermore, a user can pass in an address to some arbitrary "test_data", * was previously set by the user to hold some information that the function * will use during the testing of the test_object. * * This API does not know (and never uses) the contents of this test_data. * As an iterator is traversing objects, determining whether an object will * be returned to the user, the objects will be tested against any test- * functions that the user has defined through SE_Predicate search rules for * that iterator. */ typedef SE_Boolean (*SE_Predicate)
