Error handling...

I don't use C much, but I thought I'd mess around in it. Is try/catch C++ only? This code spits out errors with MSVC 6...

Code:

---

int main( void ) {
        try {
        }
        catch( ... ) {
        }
        return 0;
}

---

Errors:

Code:

---

g:\c++\ctrycatch\main.c(2) : error C2065: 'try' : undeclared identifier
g:\c++\ctrycatch\main.c(2) : error C2143: syntax error : missing ';' before '{'
g:\c++\ctrycatch\main.c(4) : warning C4013: 'catch' undefined; assuming extern returning int
g:\c++\ctrycatch\main.c(4) : error C2143: syntax error : missing ')' before '...'
g:\c++\ctrycatch\main.c(4) : error C2059: syntax error : ')'

Well you cannot use try catch and throw. Those are C++ specific.

** M$VC defines some M$ specific functions you can use.

They are preceeded by two underscores. Lookup __try __except __finally

There may be some sort of equivalent that I am not aware of in C but I don't think so. Some people have written libraries that act like the C++ versions; you may want to look into that.

>>Well you cannot use try catch and throw. Those are C++ specific.
Thank you. That's what I wanted to know.

Is there any standard way to do exception handling in C?

Lookup setjmp and longjmp. I generally use these for error handling in C. If you need some examples let me know.

Sure. After returning from a function, check its return value. If an error, do somthing to clean up.

Here's a project involving exception handling in C.
http://sourceforge.net/projects/cexcept/

Personally I prefer the way WaltP describes. Developing robust code means that you perform error checking in your code en error handling.
