There was a paper about exception handling in C in Software Practice and Experience back about 1981 (sorry, I dont have the exact reference on me). That handled exceptions with code like: exception FILE_ERROR; ... BEGIN f = fopen("afile", "r"); if (f == NULL) exc_raise(FILE_ERROR); ... normal case code. EXCEPTION WHEN(FILE_ERROR) ... handle file error WHEN(OTHERS) ... handle other errors. exc_reraise(); /* Pass exception out to next level */ END I have been using this code (with a few minor changes of my own) for some time. It is neat and quite clean. -- Automatic Disclaimer: The views expressed above are those of the author alone and may not represent the views of the IBM PC User Group. -- --- Duncan Booth, RCP Ltd.
