Are you saying that checking the return values of system calls should
be avoided because it makes the code to difficult to read?
I can't imagine you mean that. What do you mean? Exactly what in my
suggestion makes the code to hard to read? How can the check be made
more readable? (I can't see how GLYPH_DEBUG style handling of it
applies here.)
Remember that what I suggest is basically
if (bad_return_value) DebPrint (("error this_function.ApiFunction
=> %d", bad_return_value));
It can be visually more appealing with a macro, something like
W32DEBPRINT (this_function, ApiFunction, bad_return_value, 0);
Is that what you mean?
This is of course what I meant, but my C fu is low, and so my C
language. So we might misunderstand each other.
