cx

C experiments across a few different areas — a tiny runtime with GC, syscall mechanics in asm, and raw network programming.

Projects

Directory	What it is
stack/	Array-backed stack with automatic growth
object/	Boxed value type supporting ints, floats, strings, and arrays
ref_count/	Reference counting with cycle-safe traversal
mark_sweep/	Tiny VM with mark-and-sweep GC, handles cycles cleanly
sleep/	Sleep syscall in three ways: inline asm, extern asm, pure asm
ping/	ICMP ping from scratch

Building

Needs gcc and make. Run from any project directory:

make -C stack && ./stack/stack
make -C object && ./object/object
make -C ref_count && ./ref_count/refcount
make -C mark_sweep && ./mark_sweep/mark_sweep
make -C sleep && ./sleep/bin/sleep_c_inline
make -C sleep && ./sleep/bin/sleep_c_extern
make -C sleep && ./sleep/bin/sleep_pure
make -C ping && ./ping/bin/ping

make clean works in each directory too.
