/*
 * _KADM5_CHECK_HANDLE calls the function _kadm5_check_handle and
 * returns any non-zero error code that function returns.
 * _kadm5_check_handle, in client_handle.c and server_handle.c, exists
 * in both the server- and client- side libraries.  In each library,
 * it calls CHECK_HANDLE, which is defined by the appropriate
 * _internal.h header file to call GENERIC_CHECK_HANDLE as well as
 * CLIENT_CHECK_HANDLE and SERVER_CHECK_HANDLE.
 *
 * _KADM5_CHECK_HANDLE should be used by a function that needs to
 * check the handle but wants to be the same code in both the client
 * and server library; it makes a function call to the right handle
 * checker.  Code that only exists in one library can call the
 * CHECK_HANDLE macro, which inlines the test instead of making
 * another function call.
 *
 * Got that?
