thats not what I mean.. what I want is something like
if (function_present(foo))
x = foo();
else
x = SAFE_VALUE;
use x somehow;
so we don't have to have all modules loaded etc. the same could be done
for some syscalls, imagine
linux_foo(params)
{
if (function_present(foo))
return foo(params);
else
return ENOSYS;
}
I like this better then loading all possible modules.
