at the bottom of the turtle stack, there's a yolo-c libc that does some syscall stuff:

> libyoloc.so. This is a mostly unmodified [musl/glibc] libc, compiled with Yolo-C. The only changes are to expose some libc internal functionality that is useful for implementing libpizlo.so. Note that libpizlo.so only relies on this library for system calls and a few low level functions. In the future, it's possible that the Fil-C runtime would not have a libc in Yolo Land, but instead libpizlo.so would make syscalls directly.

but mostly you are using a fil-c compiled libc:

> libc.so. This is a modified musl libc compiled with Fil-C. Most of the modifications are about replacing inline assembly for system calls with calls to libpizlo.so's syscall API.
