good morning to all; I am new here and I shall like resolution found well has my problem in this financial year under linux (Mandriva); here is swording: under unix / linux signs correspond to software breaks. processes react to the récéption of of 3 manners: 1) to put off towards a specific function 2) to ignore the sign 3)stopping of process parmis signs they differentiate:sighup, siginit,sigkill,.. the source programmetion of signs rests on function: sigaction. let be following instructions: int a,b,c; a=10; b=0; c=a/b; 1) compile and executer this program 2) what is the shown message of error? 3) what is the sign which treats this exeption? (name and number) 4) write and execute a program in c which puts off software break: error of counting in floating vrigule (division by zero). 5) write and execute a script which shows the list of the available signs and that throws your executable program. indication: use one or several fonctions system belonging to the bookshop: #include thank you for answering me fast please.

I'm not at all embarrassed in admitting I don't know or understand anything of your problem. I suggest you try some of the other programming resources: http://www.unix.com/high-level-programming/ http://cboard.cprogramming.com/
