This function loads info from a binary data file, then loads objects
(currently 23 in the test file). Here is the loading function:
bool UnitDefLoad(cha r* sFile)
{
UnitDefCleanLis t(false); // tested. This works.
int iUnitCount = 0;
UNIT_DEF uData; // Theses objects are read from file
ifstream fin(sFile,ios:: binary);
if (!fin)
{
return false;
} // end if
else
{
fin.read((char* ) &Unit_Def_Node: :Arthur, sizeof
(Unit_Def_Node: :Arthur));
fin.read((char* ) &Unit_Def_Node: :iMonth, sizeof
(Unit_Def_Node: :iMonth));
fin.read((char* ) &Unit_Def_Node: :iDay, sizeof
(Unit_Def_Node: :iDay));
fin.read((char* ) &Unit_Def_Node: :iYear, sizeof
(Unit_Def_Node: :iYear));
fin.read((char* ) &Unit_Def_Node: :Description, sizeof
(Unit_Def_Node: :Description));
fin.read((char* ) &Unit_Def_Node: :iVersion, sizeof
(Unit_Def_Node: :iVersion));
fin.read((char* ) &Unit_Def_Node: :iBuild, sizeof
(Unit_Def_Node: :iBuild));
fin.read((char* ) &iUnitCount, sizeof (iUnitCount));
for (int iCount = 1; iCount < iUnitCount; iCount++)
{
fin.read((char* ) &uData, sizeof (uData));
UnitDefADD(uDat a);
cout << "Number of Unit_Def_Nodes: " << iUnitsDefined << "\n";
}; // end for
};
fin.close();
return true;
};
I believe the problem is the
fin.read((char* ) &uData, sizeof (uData));
in the for loop. I have 23 UNIT_DEF objects saved in the file. After
the 23rd object is loaded, it exits the loop and crashes... if I
comment out the above line, the program works fine. Is there
something wrong with my syntax? 2 1182

I don't see anything wrong with your syntax, but the syntax is not where the
problem lies. If you don't supply a complete example, it is hard for anyone
to help you. I doubt that anyone else browsing this group knows what
Unit_Def_Node is, what a UNIT_DEF is, what UnitDefADD does, what the file
contains, etc. The best advice you can get from your current post is "use a
debugger".

The second best advice would be to check to see if the calls to read()
actually succeed. The third best would be to use a text file instead of a
binary file so it's easier to follow.

Hi,
assert and error handling can be used for similar purposes.
When should one use assert instead of try/catch and in which
cases the error handling is preferable?
I've read somewhere that assert could be used to start
an interactive debugger automatically. How do I realize that
on a Linux machine using gcc?

In general, is it considered bad practice to use asserts in production
code?
What about writing a macro that does the same as assert but continues
to work regardless of the state of NDEBUG?
I can see that it would be poor style to use it for commonly
encountered errors, but what about truly exceptional errors that would
rarely if ever be encountered?

Sometimes, I can't think of any good reason why I should have the

one do about an integer overflow? Reassign values? Restart the program?
The problem will still be existing. I think that an integer overflow is

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
