Exception handling

[vkreddy_in]

HI
Currently i am handling excpetion using TRY/catch in my code.I am
looking for solution some thing like this.

if an excrption is occured then
1.call a CALLBACK function in a DLL
2.print the log message return from function call but excute the next
instruction in the current function(when i return i want to go to the
next instruction,not the instruction that was raised an exception)


i know want to know using structured excpetion handling and some
assembly language instructions can we do this?.

can some body help

thank u very much

So you've got the wrong group. comp.lang.c++ is round the corner.

You can use setjmp/longjmp to set up your own exception handling facility.
It also exists a project of exception handling, which named CException. You
can find it on www.sourceforge.net. Remember to read the comments in the
head file before you use it. Good Luck!

And where in the definition of setjmp/longjmp does the C standard
define a way to resume the function that caused the exception at the
machine language instruction right after the one that generated the
exception?

Of course, it is NOT a real exception, but a way for you to handle the
customized exception.

Thank you very much for your help,can you please tell me a way to
resume the function that caused the exception at the machine language
instruction right after the one that generated?

That's not possible without resorting to highly architecture-specific,
and possibly quite arcane, techniques. Ask in a newsgroup which
discusses your OS, compiler and hardware; do not expect the answer to
port to anything else. It certainly cannot be done in portable C.
