Definition of the TU_RETURN_TYPE output structure

The exectu( ) interface expects, as a return value, a unsigned long major_rc return code value. As an extension of this return value, a Test Unit Control Block (TUCB) return structure is included as a third argument to the exectu() function call. The TUCB return structure is defined as a C language data type called TU_RETURN_TYPE, and is defined in the diag/tucb.h header file.

typedef struct tucb_out_t {
            ulong                 major_rc;
            ulong                 minor_rc;
            ulong                 actual_loop;
            ulong                 data_log_length;
            ulong                 severity;
} TU_RETURN_TYPE;
