Error Hnadling in C

[shiva2285]

Hi
I am new to C programming
I am given a small task of doing error handling of a program.To write a small function called xit() for this reason...
The program looks as follows.

void xit(errmsg, icode)
char *errmsg;
int *icode,errCode;

{ printf(" Error occured reason - %s and Reason code %d " ,errmsg,icode);

exit(1);
}
The arguments errmsg, icode are taken from some other functions where the error message and code needs to be printed.
I need to print the Error message and the code on the terminal.

Can someone guide me how to proceed further

Is this for a class, or a job? In any case, there are several errors here, including the signature of the function declaration. You are using old style C function declaration, as opposed to standard C which would have the type information along with the variable names inside the (). You have an extra argument declared, but not in the (). You have declared a pointer to integer variable, but are passing it as an integer to the printf() function. I won't get into more specifics here since as you say, you are very new (obviously) to C programming. Spend some $$ and purchase K&R. It will prove to be one of your better investments.

Its part of my studies ...being Mechanical Engg..has not done much of programming... ,i am learning C now..so i just thought i ask the experts who can guide me in this...

Fair enough. However, though we can guide you, we cannot do your school work for you. I hope my suggestions were clear enough to get you going in the right direction. FYI, K&R is the Kernighan and Ritchie book "The C Programming Language". The current edition covers the ANSI standard version of the language. The "old style" that I mentioned is commonly known as the K&R style, because that's how it was done when K&R first invented the C language. I have both editions on my shelf because I started C programming long before the ANSI standard was out, back in the very early 1980's with the first C compiler available for micro-processors. Before that, you needed a PDP-8 at least to get a C compiler from AT&T.

Hi
Thanks for your replies. I was able to do it myself somehow. I changed the signature of function declaration in the header files (which was actually typed wrong) and i could make it work now.
PS: I have asked experts advise to correct me where i am wrong so that i can work from there on and i would not want someone to do all my work for me anyways.

Thanks for time and advise.
