calling os functions not in module os

[Skaperen]

i recall seeing a way to make calls to libc functions and/or kernel syscalls but now that i need it it can't find it. i did find module dl but it was depricated in version 2.6 so that is not what i would use, even if i could. i'd rather not name the calls i want to make so that any answers can stay focused on what is a general way to do Linux syscalls. at least one of the syscalls i want to do is not even in gnu libc. i also recall seeing a way to call a C library. but that might not help for the one syscall that is not in libc unless i can find a way to build my own C library to do it.
