[Dev-C++] error handling

[Sam <sch...@ho...>]

Hi there,=20
I am trying to add an error handler for a C program for a class =
assignment.  we haven't gone over errorhandling but i'm getting that =
awful message

"This program has performed and illegal operation and will be shut down" =
in regards to this statement.

 if((fp =3D fopen("data.dat", "r")) =3D=3D NULL)

basically if no file exits to read, I get the message.

What I have so far is below, but I keep getting a message from the =
compiler stating that _HARD_IGNORE not declared.  I thought this was a =
constant in the dos.h library??

way confused....does it make sense to do this at all?


void handler(unsigned device_error, unsigned error_code,
                 unsigned *device_header)
{
     cputs("Critical error resuming program\n");
     _hardreturn(_HARDERR_IGNORE);           =20
}

[Dev-C++] error handling

[Noorez K. <dar...@ho...>]

I am having trouble with my try,throw and catch statments.

I tried to do this...

try
{
    //try to do whatever
    throw "Did not work"
}
catch(char* error)
{
   cout << error;
}

This did not work. The program quits with the error message abnormal program 
termination.
But if I change  " char* error " to " ... " then the catch statment will 
work. Why didn't it work before?
