39              **     MI_RETURN_ERR(EXPR)

41              ** These override the macros with the same names in MI.h and add printf
42              ** tracing on onon-zero MI_Result objects (those not equal to MI_RESULT_OK).
43              ** Functions that use these macros can enable tracing of bad return values
44              ** by simply including this file.
