Catching run time errors from unmanaged code

[Manish Soni]

My C# code invokes some unamanged code. My goal is to somehow catch any time
error in the unmanaged code. I want to capture that a show a user friendly
exception to the end user.

Most of the time you return an int value from unmanaged code, then check
that value from within your managed code. Usually a zero indicates no
errors/successful completion of unmanaged code; other values can indicate
various error conditions you wish to trap.
