SEH?

[Eu Genek]

Hello,

Ultimately, I'm trying to prevent the operating system (WIN XP) from terminating my program when my program does something silly. If someone has a nice example on how I can go about that, I'd appreciate it greatly.

In my search for the answer I found the following I wanted to try. However, I am getting an " `_set_se_translator' undeclared " error.

include <windows.h>

include <iostream>

struct SEHException
{
SEHException(const EXCEPTION_RECORD & record)
: record(record)
{}

EXCEPTION_RECORD record;

};

void translator_function(unsigned int, EXCEPTION_POINTERS eps)
{
throw SEHException(eps->ExceptionRecord);
}

int main()
{
try
{
_set_se_translator(&translator_function);
// stuff
}
catch (SEHException & e)
{
// handle the exception
}
return 0;
}

I have tried setting the "Enable Exception Handling" option under both project and compiler tabs. It didn't help.

The compile log. I'm using Dev C++ 4.9.9.2.

Execution terminated

Thanks.

Thanks Clifford,

I eventually made it there. It took some time though. I was frustrated by snippets of code here and there which don't tell me which headers are required.

Anyways, I don't have <eh.h> on my PC so I'll have to get that somewhere.

I did, however, find another solution for my problem. This uses <csignal>, which I do have, and seems a little simpler than the above.

include <csignal>

void cleanUp( int dummy )
{
// Error recovery / cleanup code/ pseudo graceful exit.
}

int main()
{

// Connect various signals to our clean-up function
signal( SIGSEGV, cleanUp);
signal( SIGABRT, cleanUp);
signal( SIGTERM, cleanUp );
signal( SIGINT, cleanUp );

// The above weren't catching Divide by Zero or Access Violation Errors
// so I just did the following, which does.
for ( unsigned int i = 0; i != 255; ++i)
{
    signal(i, cleanUp);
}


// Some code to reproduce access violation error / divide by zero / etc...

}

Now, I just have to figure out why my program is crashing in the first place...

Again, thanks for your time.

Well the code calls _set_se_translator() but there is no declaration for it. You have only included <windows.h> and <iostream> and it is not declared in either of those.

The documentation ( http://msdn.microsoft.com/en-us/library/5z4bw5h5(VS.80).aspx ) clearly states <eh.h>. You read the documentation right?
