you know how main() can be declared with varying parameter counts,
like
int main()
or
int main( int argc, const char* argv* )
and even more. Does this work for any function? If I pass a function
more parameters than it actually uses, is that safe with OS X's
current Mach-O ABIs?
Last I knew, that was a part of the C language standard.
And it works too. Lots of Unix APIs depends on that. Off the top of my
head, the third argument of open() is optional and signal handers were
originally defined to take one argument, but now they take three. Old
handlers will obviously work, since they ignore the second and third
arguments.
